How much kPa is too much?
One thing that is important for proper driving conditions is proper tire inflation and pressure. The ideal range of pressure in cars is between 193-234 in kPa (kilopascal) or 28 to 34 psi (pounds per square inch). However, in heavier cars, such as minivans, the pressure can be higher, upwards to 303 kPa (44 psi).
How is the pressure of a tire rated?
Each tire is rated with a load range, load index number, and max pressure rating. Passenger tires will be rated Light Load (LL), Standard Load (SL), or Extra Load (XL). Extra Load tires of the same size will typically have the same load capacity at the same pressure as the Standard Load tire.
What should the pressure be on a SL tire?
The maximum allowed pressure listed on a tire’s sidewall can be higher however. Some tires list 44 psi and many higher speed tires will list 50-51 psi. This added pressure does nothing for load capacity. Pressures above 35-36 psi for SL tires and 41-42 psi for XL tires will not increase the load capacity of the tire.
How often should you check your tire pressure?
Many smart drivers check their tire pressure every time they fill up their gas tank. Keep a handheld pressure gauge in your car and you can perform a quick check while you’re filling up. If that seems excessive, try to check your tire pressure at least once a month.
Where can I find the correct tyre pressure?
If you are using your vehicle to carry an additional load or weight, always consult your vehicle handbook for the correct laden pressure. If the tyre size shown does not match the tyre size on your vehicle, please contact your local Kwik Fit Centre.
