Introduction: Why Your Gravel Tyres Matter More Than Your Groupset

Here is a truth that most cyclists take far too long to learn: the single biggest performance difference you can make to your gravel bike is not a lighter wheelset, not an electronic groupset, and certainly not a carbon handlebar. It is your tyres. Those two rubber contact patches — each roughly the size of a thumbprint — are the only things connecting you to the ground. They determine your grip in corners, your rolling speed on tarmac transfers, your comfort over washboard surfaces, and whether you stay upright when a rain shower turns packed gravel into a skating rink.

We have spent the better part of eighteen months testing gravel tyres across terrain that ranges from bone-dry Mediterranean hardpack to sodden British bridleways, from smooth Alpine tarmac to loose volcanic gravel in the Canary Islands. The goal was simple: find the best gravel tyres for riders who face genuinely mixed terrain — not pure road with a token gravel sector, and not full-on mountain bike singletrack, but the honest blend of surfaces that defines modern gravel riding.

This guide is for the rider who leaves home not entirely sure what the trail will throw at them. Perhaps your local loop starts on tarmac, transitions to a compacted forestry track, crosses a muddy field, descends a rocky doubletrack, and returns home on more road. You need a tyre that does everything reasonably well rather than one thing perfectly. That is the brief we tested against.

We narrowed the field to five tyre families from the brands that consistently deliver at the highest level: Panaracer, Schwalbe, WTB, Pirelli, and Continental. Each offers multiple tread patterns and widths, but we focused on the models most suited to mixed terrain in the 40-45mm range — the sweet spot where rolling efficiency meets off-road capability.

Every tyre was tested tubeless on 23mm internal width rims at pressures between 2.2 and 3.2 bar depending on terrain. We assessed grip on hardpack, loose gravel, wet mud, and tarmac. We measured weight on calibrated scales rather than trusting catalogue claims. We tracked puncture events over thousands of kilometres. And we noted subjective qualities — ride feel, confidence in corners, feedback through the bars — that numbers alone cannot capture.

Whether you are building up a new gravel bike, preparing for a bikepacking adventure, or simply tired of your current tyres letting you down when the trail gets interesting, this guide will help you make the right choice. Let us get into it.

The Panaracer GravelKing SS+ is the tyre we kept coming back to throughout our testing period. The “SS” stands for semi-slick, but that undersells what this tyre offers — the centre tread features a dense array of low-profile knobs that transition to more pronounced shoulder lugs, creating a tyre that rolls fast on hardpack and tarmac but still bites when you lean into corners on loose surfaces.

Panaracer’s ZSG Natural+ compound is the real star here. It uses a higher proportion of natural rubber than previous generations, and the difference in wet grip is immediately noticeable. Where the original GravelKing could feel sketchy on damp tarmac, the SS+ inspires genuine confidence. Rolling resistance is rated at approximately 22 watts per tyre at 3.0 bar on a drum test — not quite road-tyre territory, but remarkably close for something with meaningful off-road capability.

In our testing across Catalan gravel tracks, the 40mm version proved ideal for routes that mix 40-50% tarmac with dry to moderately loose gravel. The 43mm version earned its place on wetter days and looser terrain, where the extra volume allows you to drop pressure to 2.3 bar without risking rim strikes. At that pressure, the SS+ conforms beautifully to irregular surfaces and maintains traction that belies its relatively conservative tread pattern. We logged over 3,800 km on one set of 40mm SS+ tyres before the centre knobs showed significant wear — excellent longevity for a performance-oriented gravel tyre.

Tubeless setup was straightforward on every rim we tried (Hunt 35, DT Swiss GR1600, Roval Terra CL). The tyres seated with a floor pump on all three wheelsets, though the DT Swiss rims needed a second attempt. Sealant distribution was even thanks to the smooth inner casing, and we experienced zero burps during our test period despite running pressures as low as 2.0 bar on one particularly muddy outing.

The one limitation worth noting: when conditions turn genuinely muddy — think sticky clay rather than merely damp trails — the SS+ reaches its limit. The tightly-spaced tread packs with mud and the tyre becomes a slick. For riders in consistently wet climates who face genuine mud regularly, the GravelKing SK+ (with its more open knob pattern) or a dedicated mud tyre would serve better. But for the mixed-terrain brief we set out to test, the SS+ is peerless.

Pros:

  • Outstanding balance of rolling speed and off-road grip
  • Excellent wet tarmac performance with ZSG Natural+ compound
  • Reliable tubeless setup across multiple rim brands
  • Very competitive weight for a tyre with puncture protection
  • Good longevity (3,500-4,000 km realistic)

Cons:

  • Packs with mud in genuinely sticky conditions
  • Shoulder knobs could be more aggressive for steep loose descents
  • Sizing runs slightly narrow (40mm measures 39.2mm on 23mm rim)

Best for: The rider who wants one tyre that handles everything from morning road transfers to afternoon gravel exploration without compromise.

Schwalbe’s G-One family deserves attention as a complete system rather than individual tyres. The lineup spans from the nearly-slick G-One Speed through to the aggressively-treaded Ultrabite, with the Allround sitting at the sensible midpoint. For mixed terrain riders, the Allround and Ultrabite form a particularly effective pair — Allround for dry-season riding and Ultrabite for autumn through spring.

The G-One Allround features a microsquare tread pattern that looks almost geometric from above. Those tightly-packed squares provide surprising mechanical grip on loose surfaces while maintaining a nearly continuous contact patch on smooth terrain. Rolling resistance sits at approximately 24 watts — marginally higher than the GravelKing SS+ — but the Schwalbe’s Addix SpeedGrip compound offers notably superior grip on wet rock and roots. The tyre has a planted, confident feel on technical descents that the Panaracer does not quite match.

Where Schwalbe truly excels is the G-One Ultrabite for genuinely challenging conditions. This is the tyre you mount when the forecast shows rain for the foreseeable future. The open chevron-pattern tread is genuinely self-cleaning — we tested it through Oxfordshire clay that normally packs into anything less aggressive than a mountain bike tyre, and the Ultrabite shed mud within two wheel rotations. The trade-off is a noticeable drone on tarmac and around 4 watts more rolling resistance than the Allround, but the grip in marginal conditions is transformative.

The Super Ground casing on the Evolution-level tyres deserves specific praise. It is noticeably more supple than the Performance-line’s standard casing, conforming better to surface irregularities and providing measurably better grip at equivalent pressures. The weight penalty (approximately 25g per tyre over Performance line) is worth paying. We experienced one sidewall cut in 2,600 km of testing — a sharp flint on a Wiltshire byway that would have killed most tyres — but the Super Ground casing prevented complete failure and held air long enough to reach tarmac.

Tubeless setup with Schwalbe’s TLE beading is among the best in the industry. Every tyre we tested seated on the first attempt with a floor pump, and the tight bead-to-rim interface meant zero air loss during inflation. Schwalbe’s own sealant works well, though we found Stan’s Race Day to be equally effective at lower operating pressures.

The only real criticism of the G-One family is availability. Popular sizes (40mm Evolution in particular) frequently sell out, and Schwalbe’s distribution can be patchy. If you find them in stock, buy two sets.

Pros:

  • Allround offers excellent all-surface versatility with confident cornering
  • Ultrabite genuinely works in mud where other gravel tyres fail
  • Super Ground casing provides outstanding suppleness and puncture protection
  • Best-in-class tubeless setup experience
  • Two-tyre system (Allround + Ultrabite) covers every season

Cons:

  • Ultrabite is noticeably loud and draggy on tarmac
  • Availability issues on popular sizes
  • Allround wears faster than competitors (2,500-3,000 km)
  • Performance-line versions lack the suppleness that makes Evolution special

Best for: Riders in wet climates who need genuine mud capability without going to a mountain bike tyre, or anyone who wants a seasonal tyre system.

RRP £45 / €50

The WTB Riddler is the blue-collar workhorse of the gravel tyre world. It does not have the racing pedigree of the Panaracer, the German engineering precision of the Schwalbe, or the Italian flair of the Pirelli. What it has is an almost supernatural resistance to damage, predictable grip across a vast range of conditions, and a price point that makes it the default choice for riders who measure tyres in seasons rather than grams.

The tread pattern is a proven mountain bike design scaled down for gravel — a fast-rolling centre line with progressively taller knobs towards the shoulders. It is not revolutionary, but it works. On hardpack, the low centre knobs roll efficiently while providing adequate braking traction. Lean the bike over and the taller shoulder knobs engage, offering predictable, progressive grip that lets you adjust mid-corner without unexpected breakaway. It is the kind of tyre that builds confidence because it behaves the same way every time.

At 520g for the 45mm Light/Fast Rolling version, the Riddler is not light. That weight comes from WTB’s robust casing construction, which uses a tightly-woven base layer that resists cuts and punctures with remarkable tenacity. In 4,200 km of testing across some genuinely hostile terrain — sharp slate in Wales, volcanic rock in Lanzarote, broken glass on urban cycle paths — we had precisely one puncture that sealant could not handle (a 6mm thorn that punched clean through the casing). The Tough/Fast Rolling version adds even more protection at the cost of another 45g, and we would recommend it for riders who frequently encounter sharp flints or thorns.

Rolling resistance is the Riddler’s weakness. At approximately 28 watts per tyre, it sits meaningfully behind the Panaracer and Continental in our test group. You feel this on long tarmac transfers — the tyre has a subtle but constant drag that faster-rolling options eliminate. For rides that are predominantly off-road, this matters less; the Riddler’s extra volume and casing quality provide comfort and security that compensate for straight-line speed. But if your routes involve more than 40% tarmac, lighter and faster options exist.

The 45mm width is the Riddler’s sweet spot. At this size, the tyre has enough volume to run comfortably at 2.2-2.5 bar tubeless, where it becomes remarkably comfortable over rough surfaces. The Dual DNA compound — harder in the centre, softer on the shoulders — provides a sensible compromise between longevity and cornering grip, and we measured approximately 4,800 km before the centre tread wore to the point of replacement. That is exceptional durability.

Tubeless setup is slightly more involved than the Schwalbe or Panaracer. The TCS bead is tighter, which is good for security but can make initial mounting a forearm workout. We needed a compressor for one of our test wheelsets (a Fulcrum Rapid Red) though a floor pump sufficed on the Hunt and DT Swiss rims. Once seated, the bead holds tenaciously — we never experienced a burp even at very low pressures.

Pros:

  • Outstanding puncture and cut resistance across all conditions
  • Predictable, confidence-inspiring grip pattern
  • Exceptional durability (4,000-5,000 km realistic)
  • Best value in the test group by significant margin
  • Wide size range suits everything from fast gravel to light touring

Cons:

  • Heavier than all competitors at equivalent width
  • Rolling resistance is noticeably higher than faster alternatives
  • Tight bead can make tubeless mounting difficult
  • Tread pattern lacks the wet grip refinement of newer designs
  • Centre tread buzzes slightly on smooth tarmac

Best for: The rider who wants to fit tyres and forget about them for an entire season, rides rough terrain regularly, and values durability and value over marginal speed gains.

RRP £62 / €70

Pirelli’s return to bicycle tyres has been one of the most impressive comebacks in cycling components. The Cinturato Gravel range — named after the legendary car tyre — brings Formula One-derived compound technology to gravel cycling, and the difference in ride quality is immediately apparent. The Gravel M (Mixed) sits between the fast-rolling Gravel S (Speed) and the aggressive Gravel H (Hard terrain), targeting exactly the mixed-terrain brief we set for this test.

The first thing you notice about the Cinturato Gravel M is the casing quality. At 127 TPI with Pirelli’s ProWall construction, this is the most supple tyre in our test group. It conforms to surface irregularities in a way that feels almost liquid — small vibrations are absorbed rather than transmitted, and the tyre maintains contact with the ground through undulations that would cause stiffer casings to skip. This translates directly to grip; a tyre that stays in contact with the surface provides more traction than one that bounces off it, regardless of tread pattern.

The tread design is distinctly Pirelli — a diamond-pattern centre with transitional intermediate knobs leading to relatively tall shoulder lugs. The centre rolls efficiently on hard surfaces (approximately 23 watts in our testing, second only to the Continental Terra Speed) while the shoulder knobs provide reliable cornering grip on loose material. The SpeedGRIP compound is a single-density formulation that prioritises grip over longevity — a deliberate choice that makes the Cinturato feel planted and secure but means you will replace it sooner than the WTB or Panaracer.

In our testing, the Cinturato Gravel M excelled on the kind of mixed terrain common in southern European gravel riding — dry hardpack with loose stone on top, occasional sandy sections, and smooth tarmac connectors. It feels fast and alive in a way that the more utilitarian WTB Riddler simply does not. Cornering confidence is exceptional; the transition from centre to shoulder tread is progressive and predictable, and the tyre communicates what it is doing through the handlebars with unusual clarity. For riders who value feel and feedback, the Pirelli is in a class of its own.

Durability is the compromise. We measured noticeable centre tread wear at 2,200 km, and by 3,000 km the diamond knobs were significantly rounded. For a £62 tyre, that is a harder pill to swallow than the WTB’s 4,800 km or the Panaracer’s 3,800 km. Pirelli clearly optimised for performance over longevity, and that is a valid choice — but riders covering high weekly kilometres will find the cost per kilometre steep.

Tubeless setup was uneventful. The bead is well-shaped and seated cleanly with a floor pump on all test wheelsets. Air retention is excellent — we regularly found less than 0.1 bar pressure loss overnight, suggesting the casing weave is tight and well-sealed. Pirelli’s recommended sealant volume (30ml per tyre) seemed conservative; we used 40ml and had better success sealing larger punctures.

The ProWall casing provides adequate puncture protection for normal gravel conditions but lacks the bomb-proof character of the WTB’s construction. Two sidewall cuts during our testing period (both from sharp rock edges) suggest that riders in particularly rocky terrain should consider Pirelli’s reinforced Hardwall option, available in some sizes.

Pros:

  • Best-in-class casing suppleness and ride quality
  • Exceptional cornering grip and progressive tread transition
  • Outstanding road feel for a gravel tyre
  • Excellent communication and feedback through handlebars
  • Competitive rolling resistance despite meaningful tread

Cons:

  • Shortest tread life in the test group (2,500-3,000 km)
  • Premium pricing relative to competitors
  • ProWall casing less cut-resistant than some alternatives
  • SpeedGRIP compound hardens noticeably in cold weather (below 5°C)
  • Limited availability in some markets

Best for: Performance-focused riders who prioritise feel, grip, and speed over longevity, particularly suited to dry Mediterranean and Southern European conditions.

Continental brings something unique to the gravel tyre market: compound technology developed through decades of road racing dominance. The BlackChili compound that makes Continental GP5000 the benchmark road tyre appears throughout the Terra range, and it delivers measurably lower rolling resistance than any competitor while maintaining grip that defies its minimal tread depth.

The Terra Speed is the faster of the two models, featuring a file-tread centre with micro-siping and small transitional knobs on the shoulders. At 380g for the 40mm version, it is the lightest tyre in our test group by a significant margin. Rolling resistance is extraordinary — approximately 19 watts per tyre at 3.0 bar, which is genuine road-tyre territory. On smooth gravel, hardpack, and tarmac, the Terra Speed feels like a fast road tyre that happens to be wider. It is the clear choice for riders whose terrain is predominantly smooth and dry with only occasional loose sectors.

The Terra Trail adds more pronounced tread — still conservative by gravel standards, but with meaningful knobs arranged in a directional pattern that channels water and bites into loose surfaces. Rolling resistance increases to approximately 24 watts (still competitive with the best in our group), but grip on wet and loose surfaces improves substantially. For genuinely mixed terrain, the Terra Trail is the more versatile choice, though neither Continental model matches the Schwalbe Ultrabite in serious mud.

Continental’s 180 TPI casing is remarkably supple for a tyre with meaningful puncture protection. The ProTection layer — a breaker belt positioned between tread and casing — handles thorns and small debris effectively. We experienced one puncture that defeated sealant across 3,100 km of testing on the Terra Trail, and zero on the Terra Speed (though the Speed spent less time on aggressive terrain). Sidewall protection is adequate but not class-leading; the Vectran Breaker does its job, but a sharp rock edge can still cause damage.

The BlackChili compound’s grip characteristics deserve special mention. Unlike many gravel compounds that feel distinctly plasticky on wet tarmac, Continental’s formulation maintains excellent adhesion on damp road surfaces. This matters enormously for riders who face unpredictable weather — being caught in rain on a long tarmac descent is far less alarming on Continental BlackChili than on most gravel-specific compounds.

Tubeless setup revealed the one real weakness of the Continental Terra range: bead tolerances. Of the four tyres we tested (two Trail, two Speed), one required a compressor to seat and one leaked air at the bead until we applied a second coat of tubeless tape to the rim. Once seated and sealed, air retention was excellent, but the initial setup experience was inconsistent compared to the Schwalbe and Panaracer. Continental has reportedly improved bead tolerances for 2026 production, but we tested both older and newer stock without obvious difference.

Weight-conscious riders will gravitate to the Terra Speed, and for good reason — at 380g it is 140g lighter than the WTB Riddler and a full 50g lighter than the next-lightest competitor. On climbs, that saving is noticeable. Over a full day of riding with thousands of metres of elevation, the cumulative energy savings are meaningful. The question is whether you are willing to accept reduced off-road capability for that speed advantage.

Pros:

  • Lowest rolling resistance in the test group (Terra Speed especially)
  • BlackChili compound provides exceptional wet road grip
  • 180 TPI casing is supple and comfortable
  • Terra Speed is lightest tyre tested by significant margin
  • Excellent durability for such a fast-rolling tyre (3,500+ km)

Cons:

  • Inconsistent tubeless bead seating across samples
  • Neither model handles serious mud well
  • Terra Speed reaches its limit quickly on loose descents
  • ProTection casing less robust than WTB for very rocky terrain
  • Limited colour options (black only in most sizes)

Best for: Riders on predominantly smooth terrain who want the fastest possible rolling speed with credible gravel capability; racers and fast-packers who prioritise efficiency.

Buyer’s Guide

Width: 35mm vs 40mm vs 45mm vs 50mm

Tyre width is the first decision you need to make, and it depends entirely on your terrain and frame clearance. Here is what each width bracket offers:

35-38mm suits riders on predominantly smooth surfaces — paved roads, well-maintained gravel paths, and compacted fireroads. At this width, rolling resistance is minimised and the bike feels nimble and responsive. The trade-off is reduced floatation on loose surfaces and less comfortable rides over rough terrain due to higher required pressures (3.0-3.5 bar to avoid pinch flats). Choose this width if more than 60% of your riding is on smooth surfaces.

40-42mm is the sweet spot for genuinely mixed terrain and the width we recommend for most riders. It offers enough volume to run comfortable tubeless pressures (2.5-3.0 bar) while remaining efficient enough for long tarmac transfers. Virtually all gravel frames accept 40mm tyres with generous clearance, and most wheelsets are optimised for this range. This is where the majority of our testing focused, and where we believe the best all-round performance lives.

43-45mm extends off-road capability significantly. The extra volume allows lower pressures (2.2-2.8 bar) that dramatically improve grip and comfort on rough terrain. Weight increases, and rolling resistance on smooth surfaces is higher, but for riders who spend the majority of their time on unpaved surfaces, the larger volume is transformative. This width is also excellent for bikepacking, where loaded bikes benefit from the additional cushioning. Check your frame clearance carefully — not all gravel frames accept 45mm with sufficient mud clearance.

48-50mm enters near-mountain-bike territory. These widths make sense for monster-cross builds, riders on particularly rough terrain, or bikepackers carrying heavy loads over unmaintained tracks. Rolling resistance on road is noticeably higher, and the bike handling changes — steering feels slower and the bike prefers lower speeds through technical sections. Few dedicated gravel frames accept this width; check specifications carefully.

Tread Patterns: File Tread vs Mixed vs Aggressive

File tread (Continental Terra Speed, Panaracer GravelKing slick) features minimal surface texture — micro-siping and very low-profile dots rather than distinct knobs. These tyres rely on compound grip rather than mechanical tread engagement. They roll fast, are quiet on road, and perform well on dry hardpack. They fail quickly when surfaces become loose or wet. Choose file tread only if you rarely encounter genuinely loose or muddy conditions.

Mixed/transitional (Panaracer SS+, Schwalbe Allround, Pirelli M, Continental Terra Trail) combine a faster-rolling centre with more pronounced shoulder knobs. This is the most versatile category — adequate straight-line speed with genuine cornering grip off-road. The centre provides efficient rolling on flat surfaces while the shoulders engage during lean angle, giving you a wider range of usable grip angles. This is the correct choice for most mixed-terrain riders.

Aggressive (Schwalbe Ultrabite, WTB Riddler, Panaracer SK+) feature open, tall knobs across the full tread width. They sacrifice road speed for off-road traction, with particular benefits in mud, wet grass, and loose-over-hard surfaces. The open tread pattern allows self-cleaning in muddy conditions — tightly packed knobs clog and become ineffective. Choose aggressive tread if your terrain is predominantly off-road or if wet/muddy conditions are frequent.

Tubeless Setup Tips

Every tyre in this guide is tubeless-compatible, and we strongly recommend running tubeless for gravel riding. The benefits — lower pressures, puncture sealing, reduced weight — are too significant to ignore. Here are our tips for reliable setup:

Rim tape is the foundation. Use proper tubeless tape (not electrical tape or Kapton tape) at the correct width for your rim’s internal measurement. Apply in a single continuous wrap with 50mm overlap, pressing firmly into the rim bed corners. Two layers provide insurance but are not always necessary on well-machined rims.

Valve stems should be long enough for your rim depth with 15mm of thread extending beyond the locknut. Tighten moderately — overtightening deforms the rubber seal and creates leaks. Apply a thin smear of sealant around the base before inserting.

Sealant quantity matters. Use 30-40ml per tyre for 40mm widths, and 40-50ml for 45mm. Too little sealant means insufficient coverage; too much adds rotating weight without benefit. Top up every 3-4 months as sealant dries.

Seating the bead is easiest with a completely dry rim and tyre. Add sealant after seating, not before — sealant on the bead interface can prevent proper sealing. If a floor pump cannot seat the bead, a tubeless inflator canister (Milkit, Bontrager Flash Charger, or similar) provides the burst of air volume needed.

Pressure Guidelines by Rider Weight

These pressures assume 40mm tyres, tubeless, on 23mm internal width rims. Adjust by +0.2 bar for 35mm tyres, -0.2 bar for 45mm tyres. All figures in bar (multiply by 14.5 for PSI).

Rider weight (kit + bike) Front Rear Notes
70-75kg total 2.2 2.5 Light rider, responsive feel
75-80kg total 2.4 2.7 Medium rider, good balance
80-85kg total 2.6 2.9 Medium-heavy, prioritise support
85-90kg total 2.8 3.1 Heavy rider, watch for rim strikes
90-95kg total 3.0 3.3 Maximum, consider wider tyres

Terrain adjustments: Drop 0.2-0.3 bar for loose gravel or wet conditions. Increase 0.2 bar for long road sections or sharp rocky terrain. Always run the front lower than the rear — the front tyre benefits more from the additional grip of lower pressure, and the rear carries more weight and is more prone to rim strikes.

Front/Rear Mixing Strategies

Running different tyres front and rear is a legitimate strategy that experienced gravel riders use regularly. The principle is simple: the front tyre needs grip (you cannot recover a front-wheel slide), while the rear tyre can prioritise speed (a rear-wheel slide is manageable).

Common combinations:

  • Front: Schwalbe G-One Allround / Rear: Continental Terra Speed — grip where you need it, speed where you can afford it
  • Front: Pirelli Cinturato Gravel M / Rear: Panaracer GravelKing SS+ — premium cornering feel with fast-rolling rear
  • Front: WTB Riddler / Rear: Continental Terra Trail — bulletproof security up front with efficient rear

Width mixing is also effective. Running a wider front tyre (45mm) with a narrower rear (40mm) provides steering confidence and floatation without the full weight penalty of wide tyres at both ends. This combination suits riders who find themselves frequently on loose descents where front-wheel grip is paramount.

Seasonal Considerations

Spring (March-May): Trails are drying but unpredictable. Mixed-tread tyres in 40-43mm work well. Consider aggressive front tyre if your region retains winter mud into spring.

Summer (June-August): Dry hardpack dominates. Fast-rolling tyres (Continental Terra Speed, Panaracer SS+) come into their own. Lower volumes (38-40mm) are practical as puncture risk from dried roots and thorns is at its highest — ensure good casing protection.

Autumn (September-November): Conditions deteriorate rapidly. Switch to more aggressive tread patterns (Schwalbe Allround or Ultrabite) as leaves, mud, and moisture return. Wider tyres (43-45mm) provide better grip and confidence as surfaces become less predictable.

Winter (December-February): If you ride off-road through winter, aggressive tread is essential. The Schwalbe Ultrabite or WTB Riddler in 45mm handles winter conditions with confidence. Accept slower rolling speeds as the price of staying upright. Run higher sealant volumes as temperatures reduce sealant effectiveness.


Frequently Asked Questions

What width gravel tyre should I choose for mixed terrain?

40-45mm is the sweet spot for mixed terrain. Narrower (35-38mm) rolls faster on road but struggles in loose gravel. Wider (48-50mm) floats better off-road but feels sluggish on tarmac transfers. For most riders on a typical gravel bike with clearance for 45mm, we recommend starting at 40mm and going wider only if your terrain demands it.

Tubeless or inner tubes for gravel tyres?

Always tubeless if your rims support it. Lower pressures improve grip and comfort, and sealant handles most punctures without stopping. The setup cost pays for itself in the first season through reduced puncture-related stops and the performance benefits of lower pressure. The only scenario where tubes make sense is touring in remote areas where finding sealant or a tubeless repair may be difficult.

How long do gravel tyres last?

Expect 3,000-5,000 km depending on terrain, compound, and riding style. Softer compounds (Pirelli SpeedGRIP, Schwalbe Addix) grip better but wear faster. Harder compounds (WTB Dual DNA centre) last longer but sacrifice some wet-weather grip. Rider weight, tyre pressure, and surface roughness all influence longevity. Running slightly higher pressures on rough tarmac extends tread life without significantly compromising off-road grip.

Can I run gravel tyres on road bike wheels?

Only if your frame has clearance and your rims have the correct internal width. Gravel tyres need 21-25mm internal width rims to sit correctly and present their tread profile as designed. Road rims (17-19mm internal) will cause gravel tyres to bulge outward, distorting the tread profile and creating unpredictable handling. Additionally, most road frames lack the clearance for 38mm+ tyres. Use gravel-specific or wide-road wheelsets.

What tyre pressure should I run for gravel?

For a 75kg rider on 40mm tyres: 2.5-3.0 bar (35-43 psi) tubeless. Heavier riders add 0.2 bar per 5kg, lighter riders subtract 0.2 bar per 5kg. Drop 0.3-0.5 bar for loose or wet terrain where grip is more important than speed. Always run lower pressure at the front than the rear (0.2-0.3 bar difference) for optimal grip balance. Use a digital pressure gauge rather than a track pump gauge for accuracy at these low pressures.


Conclusion: Our Final Recommendation

After eighteen months of testing across thousands of kilometres of genuinely mixed terrain, our verdict is clear: the Panaracer GravelKing SS+ in 40mm or 43mm is the best all-round gravel tyre for mixed terrain riding in 2026. It offers the best balance of rolling speed, off-road grip, durability, tubeless reliability, and value that we have found. It does not win any single category outright — the Continental is faster on road, the Schwalbe is better in mud, the WTB lasts longer, and the Pirelli feels more luxurious — but no other tyre handles the full spectrum of mixed terrain with such consistent competence.

For riders in wet climates who regularly face genuine mud, the Schwalbe G-One Ultrabite is the clear specialist choice. For those who prioritise speed above all else and ride predominantly smooth terrain, the Continental Terra Speed is unmatched. Budget-conscious riders who want to mount a tyre and forget about it for a full season should look no further than the WTB Riddler — its durability and value are exceptional. And for riders who appreciate the finest equipment and are willing to pay the compound-life premium, the Pirelli Cinturato Gravel M provides a ride quality that nothing else in this test can match.

The beauty of gravel cycling is that there is no single correct answer. Your terrain, your climate, your riding style, and your budget all influence the right choice. But if you forced us to pick one tyre to ride everything, everywhere, for the rest of this year — it would be the GravelKing SS+ without hesitation. Mount it, set it up tubeless at 2.5 bar, and go ride whatever the trail puts in front of you.
