BMW X1 Run-Flat Tire Pressure
1 Answers
The front tire pressure for BMW X1 run-flat tires should be between 2.0 and 2.3, while the rear tire pressure should be between 2.2 and 2.5. Run-flat tires, also known as puncture-proof tires, are abbreviated as RSC in English. The inflated tire sidewall is the main part that supports the vehicle's weight, especially for tires with a larger aspect ratio (the ratio of tire height to width), which have very thick sidewalls. Below is relevant information about tire pressure: 1. The recommended tire pressure should be based on the manufacturer's recommendation. The manufacturer's recommended tire pressure can usually be found in the following places: the vehicle user manual, the label near the driver's door (B-pillar), the drawer next to the driver's seat, or the fuel tank cap. 2. The manufacturer's recommended tire pressure refers to the cold tire pressure. The definition of cold tire pressure is as follows: measured after the vehicle has been parked for at least three hours or the tires have not been driven more than 2 kilometers. If you can only measure the tire pressure when the tires are hot, subtract approximately 0.3 bar (=4 psi) from the measured value to get the cold tire pressure. 3. When replacing new tires, pay attention to their softness or hardness characteristics. If you are replacing with softer tires such as Michelin, Bridgestone, or Continental, the tire pressure should be slightly higher than the manufacturer's recommendation. If you are replacing with harder tires such as Hankook, Cooper, or Maxxis, the tire pressure should be slightly lower than the manufacturer's recommendation. The adjustment range generally should not exceed 0.2 bar.
