Tire Pressure Temperature Calculator

Calculate tire pressure fluctuations based on change in ambient temperature to determine proper tire inflation adjustment.

Enter the tire pressure value and the temperature from the last time you have set or checked it, then enter current temperature to see how it affected your tire pressure levels.

For example, when last time you set your tire pressure to 32 psi the weather temperature was 70°F. So you enter 32 in the original tire pressure field, and 70 in the original temperature field. Then enter the current temperature to see if your tire inflation has increased or descreased from previously set value.
