Find the perfect front and rear PSI for your bike. Correct tire pressure improves grip, comfort, rolling resistance, and protects against flats. Need to find your tire size instead? Use our tire size calculator.
Tire pressure is one of the most important and often overlooked adjustments on your bicycle. The right PSI directly affects rolling resistance, grip, comfort, and flat protection. Running incorrect pressure costs you speed, control, and enjoyment on every ride. For a complete setup, also check your tire size compatibility.
Modern research shows that slightly lower pressures than traditionally recommended often perform better — wider tires at lower pressure can actually roll faster on real-world roads because they absorb vibrations instead of bouncing over them. This is why professional road racers have moved to 28mm+ tires in recent years. For off-road riding, see our mountain bike size calculator and gravel bike calculator for complete setup guidance.
| Tire Width | Min PSI | Max PSI | Typical Use |
|---|---|---|---|
| 23mm | 80 PSI | 130 PSI | Road racing, time trials |
| 25mm | 70 PSI | 120 PSI | Road cycling (standard) |
| 28mm | 60 PSI | 100 PSI | Endurance road, all-road |
| 32mm | 50 PSI | 85 PSI | Light gravel, commuting |
| 35-40mm | 40 PSI | 70 PSI | Gravel, touring, bikepacking |
| 45-50mm | 30 PSI | 50 PSI | Mountain biking, rough trails |
