What is the normal tire pressure of Nissan's new hackers?

As the weather began to enter the hot solar terms, caring riders began to ponder how to do some heatstroke prevention and cooling work for their cars. In summer, for a flat tire, the tire pressure needs to be adjusted. So let's explain the controversy over whether the tire pressure should be raised or lowered in summer.

General car owners have a habit of thinking, that is, the temperature is high in summer, the tire pressure is definitely higher than that in winter, and heating is easy to puncture, so turn it down. It has also been pointed out that if the tire pressure is reduced, the friction between the tire and the ground will increase exponentially, the tire temperature will rise sharply, the tire will become soft and the strength will drop sharply. In this case, if the vehicle runs at high speed, it may lead to a flat tire.

Let's analyze it. Reducing tire pressure will bring two consequences. First, grinding tires will shorten the life of tires; Second, fuel consumption will increase. Due to the hot weather in summer, especially when driving at high speed, when the vehicle speed reaches 100~ 120 yards per hour, the tread temperature will reach 80℃, even exceeding 100℃, and the internal pressure will increase.

As for increasing tire pressure, the only use is to reduce fuel consumption. However, in addition to the possibility of puncture, increasing tire pressure will also bring many unfavorable factors, such as increasing braking distance, which is not conducive to safe driving. The tire pressure of a car is generally 2.3~2.8BAR, as long as it is within this range, it is safe. However, the temperature is very high in summer. After the car is started, the tire pressure in the normal range may actually rise above 3.0BAR, so in summer, the tire pressure in the normal tire pressure range is lower, and the range of 2.3~2.5BAR is more suitable.
