Tire Pressure Calculator

Managing tire pressure is important in circuit driving.
This app calculates the cold tire pressure to set based on the target warm tire pressure. Use it to quickly set up your car on the track.
* Please note that driving with extremely low tire pressure may result in rim damage or tire burst.

Usage:

1. If you are using the app for the first time, measure the change in tire pressure during actual driving and enter correction data for tire pressure calculation from the settings. The input items are temperature, tire pressure before driving, and tire pressure after driving.
*If the tire brand, machine setting, or driving conditions change significantly, the temperature rise will also change, so update the information as needed.

2. Enter the temperature and target warm tire pressure, and the app calculates and displays the cold tire pressure.
*The temperature can be obtained online from the weather data at your current location.
*The change in tire pressure is displayed on a graph.
