26 mm road bike tire pressure chart

Recommended pressures for 26 mm (700×26) road tires by rider weight — the consensus of the SRAM AXS, Silca Pro and Pirelli Cycl-e ID calculators, computed for typical rough tarmac (the default road surface in all three calculators) with a 9 kg bike.

Quick answer · 75 kg rider

Start at 69 psi front / 72 psi rear (tubeless) or 71 / 75 psi with tubes, then adjust ±2 psi by feel.

All values in psi (divide by 14.5 for bar). Assumes a 9 kg bike and hooked rims. On hookless rims, SRAM/Zipp cap pressure at 73 psi — heavier riders on 26 mm tires will hit that ceiling.

What each calculator says

For a 75 kg rider on 26 mm tubeless, the three tools land 18 psi apart on the front wheel. That spread is normal — each brand optimises for something different.

Common questions

What tire pressure should I run on 26 mm road tires?

It depends on your weight. A 75 kg rider on 26 mm (700×26) tubeless tires should start around 69 psi front and 72 psi rear on typical rough tarmac (the default road surface in all three calculators). Use the chart above to find your weight, then fine-tune by feel.

Should front and rear pressure be different?

Yes. More of your weight sits over the rear wheel, so all three calculators recommend a lower front pressure — typically 3 psi less at this tire width.

How much lower can I go with tubeless on 26 mm tires?

Roughly 2–3 psi. Without an inner tube there is no pinch-flat risk, so the calculators subtract a small margin. The chart shows both tubeless and tubed columns.

Why do SRAM, Silca and Pirelli give different numbers?

Each brand models the problem differently: SRAM weights compliance, Silca optimises rolling resistance over surface roughness, and Pirelli scales strongly with rider weight. On this setup they spread across 18 psi (front). psi.bike shows the consensus of all three.

Values are computed from psi.bike's calibrated models of the SRAM AXS, Silca Pro and Pirelli Cycl-e ID calculators and are starting points, not guarantees. Always respect the maximum pressure printed on your tire sidewall and rim, and adjust for conditions.
