What is the appropriate tire pressure for an SUV?
2 Answers
Generally, the front tire pressure of an SUV is most suitable at 2.2, and the rear tire pressure at 2.5. The relationship between tires and tire pressure: A vehicle's off-road capability or tire pressure depends on many factors, among which the tire is an important factor, including the tire's tread pattern, diameter, pressure, etc. For the same tire, the required tire pressure varies when driving on different road surfaces. The relationship between road surface and tire pressure: When driving on good road surfaces, try to keep the tire pressure at the standard value. When driving on soft road surfaces, try to keep the tire pressure lower, otherwise, it is easy to cause the tires to slip in place.
This question really requires careful explanation. Our family's SUV has been running for over three years, and at first I often couldn't figure out the proper tire pressure. For a regular SUV in cold condition, the front tires should be 2.3-2.5 bar and the rear tires 2.2-2.4 bar for optimal safety - the exact values should be checked on the label on your door frame or fuel cap. I remember during the last maintenance at the 4S shop, the mechanic specifically wrote the recommended values on the tires with yellow chalk. When driving on highways in summer, it's best to keep the pressure 0.1 bar lower than standard, otherwise the rising pressure might cause a blowout. Last month when I was picking up my kid from school, I noticed the right front tire was flat - measurement showed only 1.8 bar left, no wonder it bumped so badly over speed bumps. Now I've developed the habit of checking monthly, always keeping a digital tire pressure gauge and air pump in the trunk.
