What is the normal tire pressure of Nissan's new hackers, and what is the appropriate tire pressure for hackers?

Summer is generally between 2.2 and 2.5. As the weather begins to enter the hot solar terms, riders who care about their cars begin to ponder how to do some heatstroke prevention and cooling work for their cars. It is necessary to adjust the tire pressure in summer when there is a puncture. So let's explain the controversy over whether the tire pressure should be raised or lowered in summer. Most car owners have a habit that the temperature is high in summer, the tire pressure is definitely higher than that in winter, and heating is easy to puncture, so it should be adjusted to a lower level. 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 do an analysis. 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, 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, increasing tire pressure will bring many unfavorable factors, such as increasing braking distance, which is not conducive to safe driving. The tire pressure value of automobile tires is generally 2.3~2.8BAR, as long as it is within this range, it is safe. However, the temperature is high in summer, and the tire pressure that was originally within the normal range may actually rise above 3.0BAR after the car is started, so in summer, we should take a lower tire pressure value within the normal tire pressure range, which is more appropriate between 2.3 and 2.5 bar.
