Is the tire pressure of Nissan hacker 3 10 high?

The tire pressure of Pacific Auto Network Nissan hacker shows 3 10 high. It is normal for the cold tire pressure to be between 2.2 and 2.5. The generally recommended cold tire pressure is 2.5, so the fuel consumption will be lower, and the tire pressure can be controlled within the safe tire pressure range of 3.0 when driving at high speed.

As the weather began to enter the hot solar term, I began to ponder how to do some heatstroke prevention and cooling work for my car. It is necessary to adjust the tire pressure in summer when there is a puncture. Therefore, the controversy about whether the tire pressure should be raised or lowered in summer is explained below.

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℃, or even exceed 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.

How does Nissan's new hacker view tire pressure monitoring? The tire pressure monitoring of Nissan's new hacker shows that pressing the menu button on the left side of the steering wheel can switch to the tire pressure page and display it in the driving computer. However, the tire pressure display will only be displayed after normal driving time. There is also recommended tire pressure at the B-pillar position of the driver's seat. Generally, the recommended tire pressure refers to the tire pressure measured when the tire is cooled. Tire cooling conditions are defined as at least three hours after parking or no more than 2 kilometers after driving. If the tire pressure can only be measured when the tire is hot, please subtract about 0.3 bar (=4psi) from the measured tire pressure to obtain the tire cooling inflation pressure.

Tire pressure, strictly speaking, refers to the pressure of air inside the tire. The engine is the heart of the car in car maintenance, and the damage of the engine will lead to the exhaustion of the life of the car, so the tire pressure is the blood pressure of the car, and the level of tire pressure plays a vital role in the performance and power of the car.

How to use the tire pressure monitoring of Nissan's new hackers? Tire pressure monitoring reset of Nissan new hacker. Press the menu button on the left side of the steering wheel to switch to the tire pressure page and display it in the driving computer. However, the tire pressure display will only be displayed after normal driving time.
