How to use this tire pressure converter
- Type the pressure from your gauge, dashboard, tire label, or manual.
- Choose whether the value is in PSI, bar, or kPa.
- Read the converted tire pressure and use your gauge's closest practical setting.
Tire Pressure Converter
Convert tire pressure between PSI, bar, and kPa for cars, bikes, motorcycles, RVs, and trailers. Enter the number on your gauge or sidewall chart and get the matching units instantly.
Convert tire pressure
Try a common car setting like 35 PSI, 2.4 bar, or 240 kPa.
35 PSI = 2.41 bar
kPa241 kPa
kg/cm²2.46 kg/cm²
35 PSI equals 2.41 bar and 241 kPa.

Tire pressure conversion FAQ
Is 2.4 bar the same as 35 PSI?
Very close. 2.4 bar is about 34.8 PSI, so most tire gauges will treat it as roughly 35 PSI.
What is 240 kPa in PSI?
240 kPa is about 34.8 PSI, which is also about 2.4 bar.
What tire pressure should I actually use?
Use the cold tire pressure on the sticker inside the driver's door, fuel door, frame, or the vehicle manual. The sidewall often shows a maximum pressure, not the normal recommended pressure.
Why does tire pressure change after driving?
Air pressure rises as tires heat up. That is why vehicle recommendations are usually written as cold tire pressures.
