Bike Tire Pressure Calculator
Front & rear PSI in seconds
Free · Designed for iPad. Not verified for macOS.
Front and rear pressure in seconds, from your weight and tire size. Now with rider and bike profiles. No ads, no tracking, works offline.
The right bike tire pressure in seconds: a front and rear recommendation based on your weight, your bike, your tire size and the surface you ride. Free, 100% offline, no ads, no account.
PERSONAL, NOT A GENERIC CHART
Tire pressure charts assume an average rider on an average road. This calculator uses your numbers:
• Your weight and your bike's weight (kg or lbs)
• Wheel size and tire size, with different front and rear tires if you run them
• Tubeless or tubes
• Riding surface: smooth road, rough road, gravel, technical trail, or mud, sand and snow
The result is a separate front and rear pressure, shown in psi and bar, ready to dial in with a floor pump.
EVERY KIND OF BIKE
• Road, gravel, cyclocross, touring and commuter bikes
• Mountain bikes from XC to enduro, including modern 2.4" and wider tires, and plus tires up to 3.0"
• Fat bikes up to 26 x 4.8
• Folding bikes (Brompton, Dahon, Tern), BMX, recumbents and kids' bikes on 16" and 20" wheels
Seven wheel sizes from 16" to 29" / 700C and more than 110 tire sizes, each labeled in both ISO (ETRTO) and inch formats, so you can match what is printed on your sidewall.
RIDER AND BIKE PROFILES
Save yourself and each of your bikes, then switch between them in one tap. Two riders sharing a garage full of road, gravel and mountain bikes? Every setup is one tap away. The app also remembers your last inputs, so it opens ready to use.
SENSIBLE NUMBERS BY DESIGN
The guardrails are built into the math. Surface and tubeless adjustments keep gravel and mountain bike pressures realistic, minimum pressures guard against pinch flats, and tires for small wheels follow the pressure ranges printed by their manufacturers. Treat the result as a great starting point and fine-tune a few psi to your own feel and conditions.

4. Tap Calculate
Your front and rear pressures appear instantly, in psi and bar.
MADE BY A CYCLIST
One rider, one app, and reviews that shape every update: the surface selector, saved bikes, wider MTB tires and small wheels all came from rider feedback. Something missing? Tap Send Feedback in the app and tell me.
Happy riding!
New - Rider and bike profiles: save your weight and each bike's setup, then switch between them in one tap. Pick a bike and its details fold into a single line, so the screen gets shorter, not longer. Nothing appears until you save a profile.
New - Separate front and rear tire sizes, for bikes running a wider front. Matched sizes give exactly the same numbers as before.
New - Small wheels: 16" and 20" sizes for folding bikes (Brompton, Dahon, Tern), BMX, recumbents, and kids' bikes. Recommendations follow the manufacturers' printed pressure ranges, with a dedicated BMX option.
New - 24 x 2.60 tire size, and a Send Feedback link.
Still 100% offline - no ads, no tracking, no sign-in.
