Tyre Pressure Check
Tyres last longer, vehicles are safer, and fuel efficiency is maintained when the proper tyre pressure is maintained.
What should the pressure on my tyres be?
Finding the correct tyre pressure for your car can be challenging because many different vehicle types and tyre selections are available. Fortunately, Kwik Fit has developed a tool that will show you the recommended tyre pressure for your car.
Search Using Vehicle License Plate
Always refer to your vehicle manual for the recommended laden pressure if you use your car to carry an extra load or weight. Also, please get in touch with Kwik if the tyre size displayed does not match the size of the tyres on your car.
By entering your vehicle’s licence plate below and pressing “Search,” They can determine your car’s tyre pressure.
Why Proper Inflation Is Essential
Tyres last longer, vehicles are safer, and fuel efficiency is maintained when the proper tyre pressure is maintained.
The amount of air pumped into the inner lining of your car tyre is measured in pounds per square inch (PSI) or British atmospheric pressure (BAR).
Your responsibility as the driver is to ensure that the pressure is checked and adjusted regularly. The manufacturer of your vehicle will specify the ideal pressure for your tyres. To ensure optimal tyre pressure, we advise doing this every two weeks.
You may have a slow puncture if your tyres consistently lose a significant amount of pressure, in which case you should think about getting new tires.
Correct Inflation
Under inflation
Over Inflation
Low tyre pressure
It can happen very quickly if you don’t frequently check the air pressure in your tyres. If underinflated for a while, underinflated tyres will have unequal contact with the ground and show severe wear on the inside and outer margins of the tread. Low tyre pressure causes your tyres to wear out more quickly, in addition to increased rolling resistance on the road, which reduces fuel efficiency and raises CO2 emissions.
Tyre inflation issues
On the other side, over-inflating your tyres can also be expensive and dangerous. Smaller contact patches, or the area of the tyre that makes contact with the road, are characteristics of over-inflated tyres, which can result in traction loss and longer stopping distances. Additionally, excessively high tyre pressure will result in significant, uneven wear across the centre of the tyre, shortening its lifespan relative to when it was correctly inflated.
Proper tyre pressure
Your tyres’ air pressure may not always be evident to you, but it typically leaks out at a rate of up to two PSI monthly. In addition, warmer weather typically sees increased air loss, necessitating more frequent inspections.
The recommended tyre pressure for your car can be found in the owner’s manual or printed on the driver’s door sill or the interior of the fuel tank flap. Make sure you are aware of these recommendations because your vehicle’s manufacturer may recommend different tyre pressures for your front and rear tyres. Use our tyre pressure finder as an alternative.
When your tyre is cold, always check the pressure with a tyre gauge. Finally, always refer to your vehicle manual for the recommended loaded tyre pressure if you drive your car to tow something heavier or carry additional cargo.
Do Electric Vehicles require a different tyre pressure?
Electric vehicles will likely require higher tyre pressures due to the additional weight of the big batteries inside. Nevertheless, you should always adhere to the manufacturer’s advised tyre pressure for your car’s particular make and model, which will take these factors into account. Maintaining the proper tyre pressure on electric vehicles is equally crucial because underinflated tyres will have increased rolling resistance and reduced driving range.

Converter for Tyre Pressure Measurement
The units of pressure used by automakers to determine the ideal tyre pressure for a specific vehicle are bar and psi.
Using the chart below, you can change psi into bar and bar into psi:
