pierce the hole:
Have your car tires been punctured? If so, how long ago was it? In fact, for a car that has been repaired, even if it is no problem to use it temporarily, its endurance under extreme load will be much lower than 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.
When a car drives through pits, obstacles and road edges at high speeds, the tires locally will be severely deformed under the huge impact force, and the internal pressure will increase instantaneously. The direct consequence of this is that the tires will bulge.The tires that have been bulged must be replaced immediately, otherwise there is a risk of a tire blowout.
Generally speaking, the tires of a family car in normal use can be replaced every 60,000 kilometers or two years, but tires with severe pattern wear should be replaced early. 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, increased tread cracks are also a sign of serious tire aging. Usually, car owners can properly spray some tire protection wax, and try not to press corrosive liquids when driving.
For a front-wheel drive vehicle, the front wheels sometimes look a little flat because the engine, gearbox and other important drive components are pressed on the front. The visual inspection is inaccurate, you must use a dedicated tire pressure gauge to measure whether the tire pressure is normal.
Some car owners often hear that their car makes noises when driving, but there is no malfunction when driving. At this time, you should check if there are any small stones stuck in the tire pattern. In fact, it can be solved by taking the time to dig out these small stones in the tread pattern with the key.
If you want the spare tire to play a real emergency role, you should also pay attention to its maintenance at ordinary times. First of all, check the pressure of the spare tire frequently; secondly, pay attention to the prevention of oil corrosion on the spare tire. The tire is made of rubber, so you are afraid of being corroded by various oils. The tires will bulge and corrode soon after being stained with oil, which will greatly reduce the service life of the tires; *After that, the life of the spare tire is about 4 years. Many car owners mistakenly believe that the spare tire is always new if it is not used, but it is actually over. Even if the spare tire has not been used once in 4 years, it needs to be replaced, otherwise the spare tire will become a waste tire.
