How to Use the Bicycle Tire Pressure Calculator
Correct tire pressure affects safety, comfort, rolling efficiency, and flat resistance. Select your bike type, road surface, and rider weight to get a recommended PSI range. Always stay within the maximum PSI printed on the tire's sidewall. Check pressure before each ride — bicycle tires naturally lose 1–2 PSI per day.
Pressure Guide by Bike Type
| Bike Type | Paved Road | Gravel/Trail |
|---|---|---|
| Road (700×23c) | 90–120 PSI | 80–100 PSI |
| Hybrid | 60–80 PSI | 50–65 PSI |
| MTB (29") | 35–45 PSI | 22–32 PSI |
Frequently Asked Questions
How often should I check my tire pressure?
Road bike tires: before every ride. Mountain bikes: at least weekly. All bicycle tires lose air gradually — even without a puncture. A floor pump with a gauge is the most reliable way to check.
Does tubeless change the recommended pressure?
Tubeless systems allow running 5–10 PSI lower than tubed setups, since there's no inner tube to pinch. Lower pressures improve traction and reduce rolling resistance on gravel and trails.
