What is the appropriate tire pressure for an SUV in kPa?
2 Answers
The appropriate tire pressure for an SUV is generally around 220-250 kPa. However, to determine the exact recommended tire pressure for your specific SUV, you can refer to the vehicle's user manual or check the label near the door (around the B-pillar or C-pillar), which usually indicates the manufacturer's recommended value. According to the international GBT2978-2008 standard, the standard tire pressure ranges from 220 to 250 kPa for standard tires, and 280 to 390 kPa for reinforced tires. The maximum tire pressure should not exceed 350 kPa. The normal tire pressure varies depending on the type of tire, so it is essential to ensure that the tire pressure remains within the corresponding range.
I usually drive an SUV, and the tire pressure is typically most suitable within the range of 220-250 kPa. It's best to check the label on your car's door frame or fuel tank cap for the exact numbers, as they vary for each vehicle. My car specifies 230 kPa for the front tires and 240 kPa for the rear tires, and I slightly increase it by 5-10 kPa in winter. Remember to use a tire pressure gauge when the car is cold for accurate measurement, meaning the car has been parked for more than three hours or driven less than two kilometers. Last month, I noticed the front tire was leaking and the pressure dropped to 200 kPa, which made the car noticeably more fuel-consuming and shaky, so I quickly went to a gas station to refill it. Insufficient tire pressure is particularly damaging to the sidewalls of the tires and can even lead to a blowout in severe cases.
