Tire Pressure Temperature Calculator

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

Enter the weather temperature and tire pressure in psi when you last checked or set 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 in °F degrees to see if your tire pressure increased or descreased from previously set value.
