🛞 Tire Pressure Converter
PSI, kPa and bar conversion
About this calculator
Your car's recommended tire pressure is usually listed in PSI, but many gauges and air pumps — especially in Canada — read in kPa. Enter a value in PSI, kPa, or bar and convert instantly between all three. It also shows the typical passenger-car range so you can sanity-check whether a reading looks right.
Tip: check pressure when tires are cold (before driving) — driving heats the air and raises the reading by several PSI, giving a false high.
