23 mm road bike tire pressure chart
Recommended pressures for 23 mm (700×23) 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.
Start at 81 psi front / 85 psi rear (tubeless) or 83 / 88 psi with tubes, then adjust ±2 psi by feel.
Pressure by rider weight
| Rider weight | Tubeless | With tubes | ||
|---|---|---|---|---|
| Front | Rear | Front | Rear | |
| 50 kg (110 lb) | 60 | 63 | 63 | 66 |
| 55 kg (121 lb) | 64 | 68 | 67 | 70 |
| 60 kg (132 lb) | 69 | 72 | 71 | 75 |
| 65 kg (143 lb) | 73 | 77 | 75 | 79 |
| 70 kg (154 lb) | 77 | 81 | 79 | 83 |
| 75 kg (165 lb) | 81 | 85 | 83 | 88 |
| 80 kg (176 lb) | 85 | 89 | 87 | 92 |
| 85 kg (187 lb) | 89 | 94 | 91 | 96 |
| 90 kg (198 lb) | 93 | 98 | 95 | 100 |
| 95 kg (209 lb) | 97 | 102 | 99 | 104 |
| 100 kg (220 lb) | 101 | 106 | 103 | 108 |
| 105 kg (231 lb) | 104 | 110 | 107 | 112 |
| 110 kg (243 lb) | 108 | 114 | 111 | 116 |
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 23 mm tires will hit that ceiling.
What each calculator says
For a 75 kg rider on 23 mm tubeless, the three tools land 26.8 psi apart on the front wheel. That spread is normal — each brand optimises for something different.
| Calculator | Front psi | Rear psi |
|---|---|---|
| Silca Pro | 84.5 | 90.1 |
| SRAM AXS | 65.7 | 70.7 |
| Pirelli Cycl-e ID | 92.5 | 94.6 |
| psi.bike consensus | 81 | 85 |
The chart assumes a 9 kg bike on typical rough tarmac (the default road surface in all three calculators). The calculator lets you set bike weight, seven surface types, hookless rims and tubeless — and ask follow-up questions.

It depends on your weight. A 75 kg rider on 23 mm (700×23) tubeless tires should start around 81 psi front and 85 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.
Yes. More of your weight sits over the rear wheel, so all three calculators recommend a lower front pressure — typically 4 psi less at this tire width.
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.
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 26.8 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.
