How much tire pressure should I hit in winter? Do this and drive your car for ten more years!

According to the Wuwei Public Security Traffic Police:

Tire pressure has an important impact on safe driving,

tire pressure that is too high or too low,

Are easy to bring damage to the tires and the whole vehicle,

At the same time, in different seasons,

There are also some differences in the standard of tire tire pressure,

So how much tire pressure is appropriate for driving in winter?

Let's come to Kangkang!

Tire care class

1. What is the harm of high tire pressure

Tire pressure is too high, the contact area between the tire and the ground is reduced, the pressure and wear per unit area increase sharply, which is easy to cause the brake to run out of control, and when the ground protrusion or depression is encountered, the tire will burst, damaging the suspension system of the car, and there will be discomfort in riding.

2. What is the harm of low tire pressure

The tire pressure is too low, so that the tire and the ground contact area increases, the temperature in the tire is abnormally increased when driving, at the same time, due to the serious deformation of the sidewall, the aging of the internal wire and curtain layer is aggravated, thus laying hidden dangers for the puncture tire, and increasing the fuel consumption and reducing the life of the tire.

3, the standard tire pressure in the end is how much

The original tire pressure standard of the passenger car is 2.3-2.5 bar, of course, different models, the weight is not the same, the tire is not the same, the tire pressure standard is not the same.

Where to find the standard air pressure of the tire?

(1) Vehicle user manual.

(2) The label next to the cab door (near the B-pillar).

(3) Drawer next to the driver's seat of the vehicle.

(4) Small door with fuel tank cover.

(5) The tire pressure of the car is near the doorpost or the fuel tank cover, or look at the side of the door of your co-pilot.

4. Tire pressure is adjusted according to the season

Summer is hotter than winter, and tires will expand and contract with the heat of the weather, so the tire pressure in winter is a little higher than in summer. However, in the case of ice and slippery road surface, the tire pressure should not be too high, although it can reduce wear, but the tire pressure will affect the adhesion of the tire.

How much tire pressure is appropriate for driving in winter? Generally speaking, the front tires 2.2-2.3 and the rear tires 2.4-2.5 in the cold car state belong to the normal range. Specifically, the tire pressure marked on each vehicle shall prevail.

5. Tire pressure of spare tires

In addition to the commonly used 4 tires, you should also pay attention to the tire pressure of the spare tire. Due to the rare use of spare tires, the tire pressure should generally be higher than 2.5. Adjust to the appropriate tire pressure when used, inflate to a high tire pressure of 2.5-3.0 bar after use.

Good reminder

In addition to tire pressure, the maintenance of winter tires also needs to pay attention to many small details. If you are driving on a road with poor road conditions due to low temperatures, you need to be more cautious. If a foreign body is stuck in the tire, it needs to be cleaned up in time to prevent damage to the tire.
