Tire maintenance safety knowledge, car tire pressure

Regularly check the tire pressure. The tire must be inflated to the corresponding pressure specified for different types and specifications of tires according to the standard. According to the vehicle equipped with tires, inflation can be carried out according to the recommended front and rear wheel pressure after consultation between the car manufacturer and the tire manufacturer.
After a period of use, the size of new tires will change (expand), and the corresponding internal pressure will decrease. When we find that the tire is flat and the air pressure is insufficient, we need to increase the air pressure enough to reduce the damage of low air pressure to the tire. (Attention: After each inflation of the tire, check for air leakage at the valve with soapy water and tighten the valve cover to avoid useless work. At the same time, the spare tire of the vehicle should be kept in a usable state at all times.) Tire maintenance safety knowledge: Do not overload. For tires, at standard air pressure, if the load is too high, it is similar to low air pressure, so faults that may occur at low air pressure can also occur at high load. Increasing the load correspondingly increases the air pressure, while reducing the driving speed, otherwise it will be very dangerous.
Excessive load not only easily causes abnormal tire wear and seriously affects tire life, but also easily leads to safety accidents. Therefore, we need to pay special attention and strictly follow the vehicle configuration. Use speed. The faster the speed of driving on the highway, the higher the possibility of tire slippage, increased heat generation, and shortened tire service life; The second heat increases, and if the heat dissipation effect is not good, it is prone to malfunction; Thirdly, due to excessive speed and frequent excessive braking, it consumes a lot of tires and is not conducive to their long-term use. So we should try to control the speed of the vehicle as much as possible, not exceed the tire's usage speed, and reduce safety hazards. Tire maintenance safety knowledge: Tires should be rotated for use. Due to the influence of braking devices, the front wheels are prone to eccentric wear. The rear wheels, on the other hand, wear more severely due to heavy loads, especially when used as driving wheels. So it is important to exchange tire positions in a timely manner. It can reduce uneven wear and tear to a small extent, thereby fully utilizing the effectiveness of each tire and extending its service life. Timely tire rotation can also detect issues with the vehicle's tilt angle and other aspects as early as possible.
Pay attention to the tire inflation steps. Tire inflation should be divided into two steps. First, fill a small amount of air to ensure that the tire is correctly installed on the wheel rim, and then continue to inflate to standard pressure. The wheel rim line on the sidewall should be completely exposed outside the wheel rim. It is also important to drive safely. Tires cannot deflate due to increased air pressure after high-speed driving; Try to avoid sudden starting, sudden braking, and sharp turns; Eliminate overloading and speeding; Slow down and drive carefully in special weather or environments (such as rain, fog, snow, mud, paths, etc.); For poor road conditions, try to avoid severe impacts on the tires as much as possible; Slow down when encountering a bend; Maintain appropriate distance between vehicles while driving; Regularly inspect, maintain, replace, and repair tires; Repaired tires are prohibited from being installed on the front wheels for use; The tire must be replaced when it reaches the wear mark; If a tire is found to be faulty, it should be replaced immediately, etc. Doing these things in daily life not only has certain benefits for tires, but more importantly, it provides a guarantee for our personal health. So everyone, please pay more attention.

The hazards of insufficient tire pressure:
1. The tires are too soft, and the contact area between the tires and the ground is too large, which increases the driving resistance and fuel consumption;
2. The part of the tire in contact with the ground is deformed greatly, which can easily cause fatigue in the rubber and inner fabric of the tire over time, affecting the service life of the tire;
3. Increase the ground contact area, which greatly increases the possibility of tire puncture when there are iron nails or glass shards on the road surface;
4. Decreased braking performance.
The hazards of high tire pressure:
1. The vehicle is bumpy and the ride comfort is reduced;
2. Small contact area with the road surface and decreased grip;
3. There is a risk of tire blowouts during summer or high-speed driving.
