Bicycle tire pressure calculator

As a rule of thumb: The thinner the tire, the higher the pressure and vice versa. A thin road tyre would have 6-8 bar of pressure, much like a road bike (have a look at our tyre pressure calculator for road bikes), while for a fat bike tire, a pressure of 0.5 bar will suffice.

Each wheel and tire combination has a tire pressure sweet spot with a 3-5 psi margin either way. This sweet spot gives the tire the correct shape, a good amount of traction, and rolling resistance. Finding your right tire pressure is the key to having the best experience on the trail. But often, this is easier said than done.On smooth surfaces like the one used in the tests shown above, moderately high tire pressure – say 100-110 psi for a 25 mm tire – actually rolls slower than either a lower pressure (80 psi) or a higher pressure (130 psi). On rough surfaces, higher pressures roll significantly slower.Time Trial Bike Tire Pressure Calculator. Last Updated on 09 May. Fat Bike Tire Pressure Calculator. Last Updated on 09 May.

With tyres, two big factors impact the rolling resistance. Firstly, the amount of tyre deformation. Tyres deform to meet the road surface, and the lower the pressure, the more deformation takes place. That process uses energy and creates rolling resistance. That's why, for a long time, we all thought that higher pressures were faster.Based on the results of extensive rolling resistance tests and measurements of tire drop under different weights, as published in the winter 2021 issue of Bicycle Quarterly, Jan Heine at the team at Rene Herse Cycles ( @reneherse) just launched a handy tool that helps you calculate what they say is the ideal tire pressure for comfort …Find the optimal tire pressure for your bike with this online tool.
