Car " foot " usually silently serve the host. In fact, no matter how fast the car can run, it will not be a good thing to leave these four feet. However, such a key part is the most vulnerable. Today Xiaobian teaches you several methods of self checking tires.

1. pierced hole

Is your car tied over a tire? What if it was so long before? In fact, it is not a problem for a tire that has been filled for a long time, but it will not be much better under the limit load. In addition, if there are more than 3 holes in the same tire, we suggest that you change it as soon as possible.

2. drum package

If a car passes through a pit, an obstacle and a road tooth at a high speed, the tire will be deformed seriously under the huge impact force, and the internal pressure will increase instantaneously. The direct consequence is that the tire cord is broken and the drum is caused. Moreover, under the same impact, the low flat ratio tire is more likely to cause sidewall bulging than the high flat tire. Bulging tires must be replaced immediately, otherwise there will be a risk of blowout.

3. pattern

Generally speaking, a normal household car can be replaced every 60 thousand kilometers or two years, but the tire with severe pattern wear should be replaced early. Today's fast repair shops have pattern wear scales. Owners can buy one and check the tire wear pattern at any time. In addition, the increase of tread cracks is also a symbol of serious aging, usually can be properly spray some tire protection wax, and when driving, try not to press to corrosive liquid.

4. pressure

most household cars now use radial radial tires without inner tube. For the front drive, the front wheels are sometimes shriveled because of the important driving parts, such as the engine and the gearbox, so the front wheel sometimes seems to be a little flat, but the visual measurement is inaccurate, and must be measured with the specific tire pressure meter. In general, the pressure of the front wheel is between 2 PA -2.2 PPA, (because the use and design of each car are different, so it is best to refer to the manufacturer's numerical value in the instruction manual), and the summer can be properly lower.

5. stone

Some owners often hear that their car will send out ", snap ", sound, but there is no trouble in the car, then check if you have a small stone card in the tire pattern. In fact, as long as we take the time to use the key to dig out the small stones in the tread pattern, it will not only make the braking of the tire more stable, but also avoid the noise of the tire.

6. spare tire

in order to play a real emergency role in spare tire, attention should be paid to its maintenance at ordinary times. First of all, we should check the air pressure of spare tire regularly; secondly, we should pay attention to prevent oil corrosion, spare tire and rubber products, and fear the erosion of all kinds of oil products. When the tyres are stained with oil, it will soon expand, which will greatly reduce the service life of spare tire. Finally, the life of the spare tire is about 4 years. Many owners mistakenly believe that the spare tire is new. In fact, after 4 years, the spare tire will be replaced even if the spare tire is not used once. Otherwise, the spare tire will become a waste tire.
