Truck and bus tires are inextricably linked with driving safety. However, there is a misunderstanding in the domestic commercial vehicle market at present. The higher the tire pressure, the better! It is precisely because of this misconception that everyone is trying to adjust their tire pressure to 10bar (kg) or higher. Before we start, let's talk about why tire pressure is always high. In fact, the main reasons can be divided into two points. One is the legacy of history, which can be traced back to the era when the total weight of trucks and cargo was 55 tons or even higher. At that time, to ensure the load demand of vehicles, everyone would increase the tire pressure.
Although the national policy in the later period restricted the total weight of vehicles and cargo and controlled large tonnage and overload, the tire pressure of vehicles did not decrease at the same time.
Of course, historical issues only account for part of the high tire pressure. Another key factor that prevents the tire pressure from dropping is that drivers generally believe that high tire pressure tires have low rolling resistance, are more fuel-efficient and the tires will not overheat, so they try to adjust the tire pressure as much as possible. high.
