Get the right tire pressure for your bike in seconds.

Bike Tire Pressure Calculator recommends a front and rear pressure tailored to you - based on your weight, your bike's weight, your tire width, your wheel size, and whether you run tubeless. No more guessing, no more flat-feeling tires or harsh, bouncy rides.

WHY YOU'LL LIKE IT • Personalized front and rear pressures, not a generic chart • Covers road, gravel, MTB, plus and fat tires - a huge catalog of wheel and tire sizes • Results in both psi and bar • Tubeless-aware • Remembers your inputs for next time • Switch between kg and lbs

PRIVATE BY DESIGN • No ads • No tracking or analytics • No account, no sign-up • No internet connection required - it all runs on your device • No permissions requested

HOW IT WORKS Enter your weight and your bike's weight, pick your wheel size and tire size, toggle tubeless if you run it, and tap Calculate. You'll get a clear front and rear recommendation you can dial in with a floor pump.

The road recommendations are based on widely used cycling guidance; wider tires (MTB, plus, and fat) follow a model tuned to keep pressures sensible across the full range of sizes. Treat the numbers as a great starting point and fine-tune a few psi to your own feel, terrain, and conditions.

Made by a cyclist, for cyclists. Happy riding!
