You should have known that the first thing to keep a car is to keep a tire

"A good car owner is better than ten good car repair masters.". The cold winter is a test for the vehicle itself,

The tire is the focus of the test.

1、 It is very important to check the tire pressure

According to the principle of thermal expansion and cold contraction, the inflation pressure should be increased properly in winter to reduce tire wear. However, if driving on icy road, the tire inflation pressure is too high, which will affect the grip of the tire. Generally in cold winter, the inflation pressure is 10-15% higher than the standard.

In addition, the main car often check the tire inflation pressure, when it is insufficient to timely supplement.

2、 Tire service condition inspection

In case of tire bulge, tire cracks and tire cuts, please replace or repair them in time. Pay special attention to tread and edge wear.

3、 Replacement of old tires

The traction and grip of new and old tires are very different. The worn tires can't work on ice and snow roads.

Therefore, the tires should be replaced in time according to the wear condition. All the tires used have wear marks at the depth of 1.6 mm. Under the premise of normal use, when the tire wear reaches this convex place, it means that it needs to be replaced.

4、 Start stop low speed driving

In winter, if you restart after parking, you must drive at a lower speed for a period of time after starting because the tires are stiff before driving at a normal speed.

At the same time, in high-speed driving, try to avoid rapid acceleration and braking.

5、 Cleaning of foreign matters on tire surface

Pay attention to tire cleaning before and after driving. Before driving, check whether the groove of tire tread pattern is covered by ice and snow. If it is, clean it up. If the ice in the tire is very hard, do not pry and dig it by force, and do not pour boiling water on the tire. Just pour water on the tread pattern surface at room temperature.

At the same time, check whether there are stones, iron blocks, nails and other foreign matters in the groove. If so, clean them in time.

6、 The influence of anti skid chain on tire

The installation of anti-skid chains in ice and snow weather will cause damage to the tires and shock absorbers. If your flat rate of tires is very low, the wheel hub will be damaged, the tire bulge will occur, and the tire life will be greatly reduced.

It is often said that there is no trivial matter in safety.

Use and maintenance of your car's tires in winter,

It's absolutely the most important thing to use a car safely.
