Bike Tire Pressure Calculator
Get a sensible starting tire pressure for front and rear based on your weight and tire width.
How to use the tire pressure calculator
- Enter your weight and bike weight.
- Enter your tire width in millimetres.
- Click Calculate for suggested front and rear pressures.
Lower than you think is often faster
Modern thinking favours slightly lower pressures than tradition, because they roll faster on real roads and grip better. Never exceed the maximum printed on the tire.
Frequently asked questions
What tire pressure should I run?
It depends on weight and tire width — heavier riders and narrower tires need more pressure. This tool gives a starting point; fine-tune for comfort and grip.
Should front and rear be the same?
The rear carries more weight, so it usually runs a little higher than the front. The calculator reflects that split.
