Formula
The Tire Pressure Temperature Calculator uses the formula:
Adjusted pressure = Current pressure + Temperature change ÷ 10
Worked example
For example, with current pressure of 32 PSI and temperature change of -20 °F, the adjusted pressure is 30.0.
| Current pressure | 32 PSI |
|---|---|
| Temperature change | -20 °F |
| Adjusted pressure | 30.0 |
|---|---|
| Pressure change | -2.0 |

Frequently asked questions
Pressure changes by roughly 1 PSI for every 10°F change. A 20°F drop lowers a 32 PSI tyre to about 30 PSI.
Air contracts as it cools, so the same air takes up less volume and the pressure falls.
Yes. Check pressures when temperatures drop and top up to the recommended level for safety and economy.
Measure when tyres are cold, before driving, since driving heats them and raises the reading.
The Tire Pressure Temperature Calculator uses the formula: Adjusted pressure = Current pressure + Temperature change ÷ 10. For example, with current pressure of 32 PSI and temperature change of -20 °F, the adjusted pressure is 30.0.
