What is the tire pressure for the 2020 BMW X1 run-flat tires?
1 Answers
The front tire pressure should be between 2.0--2.3, and the rear tire pressure should be between 2.2--2.5. Run-flat tires: "The standard tire pressure is 240kpa-250kpa, while the reinforced tire pressure is 280kpa-290kpa. The tire pressure differs between cold and hot tires, with hot tires having about 20kpa higher pressure than cold tires. The manufacturer's recommended value refers to the cold tire pressure, which is around 230kpa-250kpa when the car is cold. However, the specific tire pressure should be based on the value marked on each vehicle. Pressure adjustment method: According to the principle of thermal expansion and contraction, in summer, the pressure can be adjusted 0.1-0.2 lower than the normal value, and in winter, it can be adjusted 0.1-0.2 higher than the normal value. The normal value here must refer to the car's manual. A reasonable pressure is 70%-80% of the maximum pressure marked on the tire, but the pressure should preferably not exceed the maximum pressure marked on the tire.
