How to convert bar to psi
psi = bar × 14.5038
For example, 2.4 bar is 2.4 × 14.5038 = 34.8 psi.

Typical car tyre pressures
Most cars run between about 2.0 and 2.6 bar (29 to 38 psi), but always use the figure for your own car, found in the door frame, fuel flap or handbook. Under-inflated tyres wear faster, increase fuel use and can overheat. See our tyre pressure guide and the tyre size calculator.
