This tire pressure temperature reference table shows the adjusted pressure for a range of current pressure values, assuming a temperature change of -20 °F. Every figure is computed with the same engine that powers our Tire Pressure Temperature Calculator, so the numbers are exact.
| Current pressure | Adjusted pressure | Pressure change |
|---|---|---|
| 8 PSI | 6.0 | -2.0 |
| 16 PSI | 14.0 | -2.0 |
| 24 PSI | 22.0 | -2.0 |
| 32 PSI | 30.0 | -2.0 |
| 48 PSI | 46.0 | -2.0 |
| 64 PSI | 62.0 | -2.0 |
| 96 PSI | 94.0 | -2.0 |
| 160 PSI | 158.0 | -2.0 |
| 220 PSI | 218.0 | -2.0 |
| 320 PSI | 318.0 | -2.0 |
How to use this table
Find the row closest to your current pressure and read across to the adjusted pressure. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Tire Pressure Temperature Calculator for a precise answer.
Need a value that is not in the table? — the Tire Pressure Temperature Calculator does it instantly, for free, with the formula and a worked example built in.
