I believe that most car owners have ridden bicycles when they were young, and they must have some knowledge of bicycle tires. Therefore, after growing up, some car owners may derive their knowledge of bicycle tires into car tires. Maybe I’m thinking, aren’t they all tires? Are they all made of rubber, so the two should be common. Therefore, this phenomenon is often seen in daily life. Many car owners like to deflate in summer and refill in winter. In fact, these practices are wrong. So, is there any knowledge of tire pressure that we have misunderstood? Just follow Aotaijun to discuss the tire pressure knowledge that we misunderstood in those years!
Misunderstanding 1. Hot weather releases air, cold weather adds air
The faster the driving speed, the higher the tire temperature will be. The higher the temperature, the greater the tire pressure. The increase in temperature will also cause the tire pressure to increase, but the increase is not so exaggerated. This rate will generally be 0.3Bar. The change. 2.5Bar itself is already very low, if the air pressure is lowered, the tire may face the risk of bulging.
Misunderstanding 2. Low air pressure is not suitable for flat tires
This is also the concept of bicycles. In fact, most of the tire burst points are located on the sidewall. The sidewall of the tire is the place where heat is the fastest during the driving process, and it is also the place where heat is dissipated. The sidewall undergoes elastic deformation every second, causing heat. The more it occurs, the more likely it is that tire bursts will occur. Therefore, low air pressure can easily cause the tire to burst. Of course, this also has a range. If the air pressure is too high, the tire is also easy to burst.
Misunderstanding 3. The air pressure is high while driving
This is still the concept of bicycles. The car’s shock absorption mainly relies on the suspension and shock absorber system, followed by the tires. Why is there no steel wire on the side of the tire? In addition to safety factors, there are also shock absorption factors. However, the weight of more than one ton plus people makes this ratio the same as that of bicycles. It’s not the same. Of course, if you hit 3.5 Bar, the tires will have very poor elasticity.
