In fact, it seems that the tire pressures of small vehicles are basically the same, but the actual situation is not like this. Because each car's weight and tire size are mostly different, the car's tire pressure will also vary. Others think that the suitable tire pressure is 2.4 or 2.5, but it may not be suitable for certain types of cars. Therefore, when the car leaves the factory, the car's standard tire pressure will be marked on the car, and some will be on the driver's side. On the B-pillar, some are on the back of the fuel tank cap. If not, there must be one on the manual. The most reasonable tire pressure is only based on the value marked on the car.
In summer, because the temperature is relatively high, thermal expansion and contraction, the normal tire pressure of the car needs to be lowered. Because the temperature is relatively high when driving in summer, the tire temperature of the car will also increase during driving, and the tire pressure will also rise accordingly. High, so in summer, the tire pressure should be lowered by 0.1 to 0.2 points; on the contrary, in winter, because the temperature is relatively low, the tire pressure should be raised by 0.1 to 0.2 points than the normal value.
What needs special attention here is that it is not good for the car's tire pressure to be too high or too low. Too high will lead to poor tire adhesion, and the vehicle can easily cause a tire blowout while driving. On the contrary, if the car tire pressure is too low, it will increase the car's fuel consumption and cause damage to the tires. It can also easily cause tire blowouts. Therefore, when inflating the vehicle, be sure to check the rating marked on the customer's car. When it comes to tire pressure, don't blindly listen to what your colleagues say about how much tire pressure is enough. Otherwise, if the tire pressure is inappropriate, customers may encounter unexpected dangers while driving.
