🚲 Bike Tire Pressure Calculator — Support

The simple way to dial in your ideal tire pressure.

Bike Tire Pressure Calculator recommends a front and rear tire pressure tailored to you, based on your weight, your bike's weight, your tire width, your wheel size, and whether you run tubeless. It works fully offline — no ads, no tracking, no account.

How to use it

1. Enter your weight and your bike's weight (switch between kg and lbs if you like).
2. Pick your wheel size, then your tire size.
3. Turn on “Tubeless” if that's your setup.
4. Tap Calculate to see your recommended front and rear pressures in both psi and bar.

Frequently asked questions

How accurate are the numbers?
Treat them as a well-judged starting point. Road recommendations follow widely used cycling guidance; wider tires (MTB, plus, fat) use a model tuned to stay sensible across sizes. Fine-tune a few psi to your own feel, terrain, and weather.

Does it need an internet connection?
No. Everything is calculated on your device, and the app requests no permissions and collects no data.

Can I see pressures in bar and psi?
Yes — both are shown for the front and rear. Choosing kg or lbs sets which unit is emphasized.

My exact tire size isn't listed.
Pick the closest width — pressure changes gradually with width, so a near match is fine. If you'd like a size added, email me (below) and I'll consider it for an update.
