Checking your tire pressures regularly helps to keep you safe on the road and save you money!

What is car tire pressure and why is it important?

Tire air pressure is measured in either pressure per square inch (PSI) or BAR pressure, which is the metric unit of atmospheric pressure equal to 14.50 pounds per square inch. Converting between bar pressure and PSI pressure is easily performed using this online conversion tool.

Keeping the tire pressure on to the recommended pressure level helps to increase the amount of time the tires can be used, it maintains fuel efficiency, and promotes better handling and therefor better overall road safety.

What is the correct tire pressure for my vehicle?

To find the recommended pressures for the tires you can easily search whatsthepressure.com’s database or check these options:

  • Your vehicle’s handbook
  • Stamped into the sill of the driver’s side door
  • Inside the fuel cap

The recommended pressure is set by the vehicle manufacturer and varies from model to model.

Why the correct inflation of your tires is important

Maintaining the correct tire pressure will help improve vehicle safety, extend the life of your tires and maintain fuel efficiency. Car tire pressure is measured by calculating the amount of air that has been pumped into the inner lining of your tire in pounds per square inch (PSI) or BAR pressure.

The manufacturer of your vehicle will specify the suitable pressure for your tires, and it is your responsibility as the driver to make sure that the pressure is checked and corrected on a regular basis. We recommend doing this every two weeks to ensure optimum tire pressure.

If your tires regularly lose pressure to a significant degree, you may have a slow puncture – and should consider a tire replacement.
