What is the normal tire pressure of a car? How much is the normal tire pressure of the car?

 In general, for all cars, the tire pressure is generally no less than 1.8bar and no more than 2.6bar. Now, many cars can reach 2.8 and 2.9. But what you need to know is that every car has a different standard. The tire pressure of each model will be written on the co-pilot's nameplate. You can read the co-pilot's nameplate to find out what the normal tire pressure of your car should be. The bigger cars have bigger, wider tyres, so the pressure is slightly higher.

We should also identify which factors also affect tire pressure:

1. Seasonal factors. The temperature of the external environment will also affect the tire pressure. The pressure will be slightly higher in winter and slightly lower in summer, generally with a difference of plus or minus 0.2. Therefore, it is generally recommended to raise the air pressure by 0.2 bar in winter based on the standard tire pressure. In summer, when the car is parked in the open air, the air pressure can be about 0.1 bar lower than the standard, so as to avoid puncture caused by high temperature.

2. Loading load. The more people you have in the same car, the higher the pressure is. That is to say, when the car is empty, the minimum tire pressure standard should be taken as the minimum tire pressure reference value; When the car is full, the upper limit of tire pressure standard is used as the reference of the theoretical maximum tire pressure.

So why do we need to know the tire pressure? What does tire pressure have to do with our car?

Air pressure is enough, the tire will be up, and the ground contact surface will become smaller, friction will become smaller, braking performance is not so good, braking distance will become longer, the advantage is fuel consumption will be a little lower, but it will be easy to burst the tire.

If the pressure is lower, the surface of contact with the ground will increase. Stick on the ground, the friction is big, braking performance is good, braking distance is short, at the same time fuel consumption will increase a bit accordingly.

The above is the relationship between tire pressure and car, I hope my answer can give you help, the above.
