I believe that most car owners have ridden bicycles when they were young, and they must also know something about bicycle tires. Therefore, when they grow up, some car owners may transfer their understanding of bicycle tires to car tires. Maybe you're thinking, aren't they all tires, and aren't they all made of rubber, so they should be universal. Therefore, this phenomenon is often seen in daily life. Many car owners like to deflate their vehicles in summer and refill them in winter. In fact, these practices are wrong. So, what other tire pressure knowledge are we misunderstood? Let's follow Aotaijun to discuss the tire pressure knowledge that we misunderstood in those years!
Misunderstanding 1. When it's hot, let out air and when it's cold, add 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 that exaggerated. This range is generally 0.3 Bar. The change. 2.5Bar itself is already very low. If the air pressure decreases further, the tire may face the risk of bulging.
Misunderstanding 2. Low air pressure is not suitable for tire blowout
This is also the concept of bicycles. In fact, most tire burst points are located on the sidewall. When the tire is driving, the sidewall is the place that heats up the fastest and is also the place where heat is dissipated. The sidewall undergoes elastic deformation every second, causing heat The more it is produced, the greater the chance of a tire blowout. Therefore, if the air pressure is too low, the tire will easily burst. Of course, there is a limit to this. If the air pressure is too high, the tire will also burst.
Misunderstanding 3. Turn on the pressure when the air pressure is high
This is still the concept of a bicycle. The shock absorption of a car mainly relies on the suspension and shock absorber system, followed by the tires. Why are there no steel wires on the sides of the tires? In addition to safety factors, there are also shock absorption factors. But with a car weighing more than one ton plus people, this ratio is the same as that of a bicycle. It's different. Of course, if you inflate 3.5 Bar, it will definitely bump because the tire elasticity is already very poor.
