Generally speaking, tires will also have a tire pressure marking, indicating the maximum tire pressure that the tire can accept. According to the principle of thermal expansion and contraction, it can be adjusted by 0.1-0.2 lower than the normal value in summer and 0.1-0.2 higher than the normal value in winter. The normal value here is required to refer to the car manual. In winter, it is best for the owner to always sort out the inclusions in the tread, otherwise the sturdy debris will remain in the tread and cause the tire to crack.
Tire pressure is usually between 2.2-2.4 kPa in summer should be normal, and in spring about 20 degrees usually keeps the tire pressure at 2.3-2.5 kPa, but with the gradual increase in air temperature and road temperature, high-speed or long-distance travel, tire pressure is very simple to rise, and simply cause a puncture, for safety, at this moment should park to reduce pressure.
In summer, the road temperature may reach 60-70 degrees Celsius, and if the tire pressure is too high when the car is driving on the road, it is easy to puncture the tire if it touches the thin part of the tire. Therefore, it is better for the sedan to maintain a tire pressure of 2.2 kPa.
If the tire pressure is too high, the contact area between the tire and the ground will be reduced, the pressure and wear accepted by the unit area will increase sharply, and the brake will be out of control, and the protrusion or depression on the ground will explode, damaging the suspension system of the car, and the ride will be uncomfortable.
