[Car owners’ home car knowledge]Tires, as the "feet" of a car, have been silently serving their owners. However, such a critical part is most likely to be "left out". Today we will teach you a few things to pay attention to when self-inspecting tires.
Make a hole
Have your car's tires been punctured? If so, how long ago was it? In fact, for a car that has had its tires repaired, even if it is OK for the time being, its ability to withstand extreme loads will also be Not as good as before. In addition, if there are more than 3 holes in the same tire, it is recommended that you replace the tire as soon as possible.
bulge
When a car drives over potholes, obstacles and curbs at high speed, parts of the tire will be severely deformed under the huge impact force, and the internal pressure will increase instantly. The direct consequence of this is tire bulging. Tires that have bulged must be replaced immediately, otherwise there is a risk of puncture.
pattern
Generally speaking, tires for family cars in normal use can be replaced every 60,000 kilometers or two years, but tires with severely worn patterns should be replaced earlier. Nowadays, repair shops have pattern wear scales, and car owners can buy one to check the pattern wear of their tires at any time. In addition, an increase in tread cracks is also a sign of serious tire aging. Usually, car owners can spray some tire protection wax appropriately, and try not to touch corrosive liquids when driving.
air pressure
For front-wheel drive vehicles, because important driving components such as the engine and gearbox are pressed against the front, the front wheels sometimes look a little flat. Visual inspection is not accurate. You must use a special tire pressure gauge to measure whether the tire pressure is normal.
stones
Some car owners often hear their car making noises while driving, but there is no problem when driving. At this time, you should check whether there are any pebbles stuck in the tire tread. In fact, you only need to take the time to use a key to dig out these small stones in the tread pattern to solve the problem.
Spare tire
If you want the spare tire to play a real emergency role, you must also pay attention to its maintenance. First of all, check the spare tire pressure frequently; secondly, pay attention to preventing oil corrosion in the spare tire. Tires are rubber products and are most afraid of being corroded by various oil products. Tires will bulge and corrode soon after being stained with oil, which will greatly reduce the service life of the tire. Finally, the lifespan of a spare tire is about 4 years. Many car owners mistakenly believe that the spare tire will always be new if it is not used. In fact, after 4 years, the spare tire will remain new. Even if the spare tire has not been used once, it still needs to be replaced, otherwise the spare tire will become a useless tire.
