Summer Is Coming, Please Check Your Tire Pressure Quickly!

Summer is coming soon, and it is the peak season of flat tires. The high road temperature in summer can easily cause the tire pressure to be too high and the tire will burst, which will lead to traffic accidents. In addition to the current rising tire prices, tire replacement Cost, it is particularly important to choose a suitable tire pressure for international tyres in the summer. But in fact, we found that there are still many friends who drive tractors maintain the high tire pressure that was used to when they were overloaded. What the hell is this?

Tire pressure and wear

At present, the 12R22.5 vacuum tire commonly used on heavy trucks, under the standard load, according to the tire model, the tire pressure is between 8.3bar-9.3bar, and the standard tire pressure of the 12.00R20 tire is 8.5 bar, and in hot summer weather, the tire pressure should be lower than the standard air pressure.

In addition to applying high air pressure to the tires, the tire expo believes that a considerable number of drivers are used to replenishing the flat tires with tire pressure as soon as the vehicle stops. At this time, the tires have not cooled down. It is difficult to obtain a standard tire pressure value whether the air pressure is supplemented or deflated. The correct approach is to wait for the tire to cool down after 4 hours of rest, and then adjust the tire pressure to the standard tire pressure.

Hidden tire pressure risks increase the risk of flat tire

So what will happen if the tire pressure is too high? The most direct feeling of excessive tire pressure is the increased degree of bumps and reduced comfort of the vehicle. The daily driving vibration intensity is high, and the severe vibration will increase the fatigue of the vehicle's walking system and steering system components, which will cause the chassis components such as suspension and other parts to age in advance, resulting in increased wear and tear of the vehicle and the possibility of flat tires. In addition, the tire pressure is too high, which will also cause abnormal wear of the tire when driving in an empty vehicle, mainly to increase the wear of the middle part of the tire running surface.

High tire pressure causes a flat tire

High tire pressure can be dangerous, and lower pressure can also cause problems. Insufficient tire pressure will increase rolling resistance, which will increase fuel consumption and increase vehicle operating costs. When the air pressure of the tire is lower than the standard air pressure, as shown in the figure: although it can increase its contact area with the ground, reduce the average pressure of the tire on the road. However, because the tire bends inward, a "bridge effect" occurs, and the middle load of the tread is smaller, and the load at the edge of the tread increases sharply, which increases the stress of the tire material. Because the pressure is unevenly distributed on the contact area, it will cause uneven tread wear, and the edges of the running surface are severely worn, and the wear is usually formed into teeth or waves.

Drivers, please go back and see if your tire pressure is too high. In the current general environment of standard load transportation, the tire pressure does not need to be deliberately high during the heavy or overloaded transportation, or should be based on the recommended air pressure on the tire. To adjust, when the outdoor temperature is high in summer, the tire pressure is appropriately reduced to make driving more comfortable and safe.
