Is It Normal for the Four Tires to Have Different Tire Pressures?

[BradyLynn]

It is normal for the four tires to have slightly different tire pressures, as long as the differences are not significant. The details are as follows: 1. Factors Determining Tire Pressure: The tire pressure of a car should be determined based on the vehicle model, especially the weight distribution ratio of the vehicle, to set the tire pressure values for all four tires. 2. Family Cars: These are typically front-wheel drive. The engine and transmission are located at the front, so the vehicle's center of gravity is concentrated in the front. Generally, the recommended tire pressure is 2.5-2.7 for the two front tires and 2.3-2.5 for the two rear tires. The front tires not only bear the weight of the engine and transmission but are also responsible for steering, so they require slightly higher tire pressure than the rear tires. 3. Luxury Cars: Luxury cars usually maintain a 1:1 weight distribution between the front and rear, meaning the vehicle's center of gravity is in the middle of the body. For such cars, the front and rear tires have the same tire pressure.
