Pressure Lab
Cycling
Describe your setup and get a front and rear pressure tuned to your surface, pace and tires.
Before you inflate
The numbers here are a modelled estimate of a fast, comfortable pressure. The app knows nothing about your specific rims, tires, valves or how well they're maintained, and it cannot judge whether your components are compatible with each other. Your component manufacturers' limits always win: if a result sits above any stated maximum, lower the pressure or change the setup.
Tubeless and hookless wheels in particular are unforgiving about over-inflation. Exceeding a rim or tire rating can blow the tire off the rim, damaging equipment and causing serious injury. Use your own judgement and ride within spec.
