Bike Tire Pressure Calculator

About this app

Safety first! Always make sure to pump up your tires to within a minimum and a maximum recommended pressure. Normally, that range is visible on the side of the tire.

Turns out, higher pressure is not always the fastest. How hard should your bike tires be? And what is the correct pressure?

There are multiple factors to consider:
* Tire size: Narrower tires need higher pressures than wide ones.
* Body and bike weight: Heavier riders need higher pressures than lighter ones.
* Grip: Tire that is too hard, won't grip - because it will not deform to the road surface, thus less rubber will be in contact with the road.
* Comfort: Ideally, you want to run a pressure that allows the tire to compress when you sit on the bike.
* Tubeless setup

What is the right tire pressure?

This app will help you easily and quickly calculate the recommended tire pressure for your road bike or MTB.

Features:
* separate readings for front and rear tire
* includes a wide list of tire sizes, from 23mm to 120mm of width and from 26" to 29" of the circumference
* supports metric and imperial scale for weight entry
* returns pressure values in both psi and bar
* useful for road bikes, city bikes, cyclocross, gravel, triathlon, aero bikes, fat tire, e-bikes, and MTB
* now featuring: tubeless setup option

Best tire pressure.

Who should use this app?
* Road cyclists
* Mountain bikers
* Bicycle commuters
* Triathletes

Next time you race, or just go out there to hit that CR or KOM/QOM on Strava, or do an epic Gran Fondo with Komoot - make sure to start with the right tire pressure.

Ratings and reviews

It seems to do exactly what I want. It asks weight, wheels, tires and gives recommended pressure. There is also a choice for tubeless, which yields lower pressure. It doesn't ask for usage or surface details. I'll add that it's better off not having a surface input. It would be hard to allow for what should be input. It's better to make our own adjustments on the fly.

Very solid easy to use app, but would like to see an option for the user to enter a specific measured tire size in mm (my tire measures 27 mm and I can only choose between 26 and 28 mm). Maybe also an option for surface conditions (smooth roads, rough roads, wet, etc) would be nice.

I found this app to be quite accurate, It suggested 75psi front and 80psi rear and I have 72psi front and 77psi rear. I ride on asphalt with some rough sections, so this needs to be taken into consideration. A lot of people think this is too low for a 25mm road tyre, but I have not had a puncture over the last year (over 5000km) If the app allowed for surface selection it would be perfect. Keep up the good work.
