Briefly introduce six self-test tires
As the "foot" of a car, tires have always been silently serving the owner. In fact, no matter how fast the car can run, there is no such thing as leaving the four legs. However, it is such a critical part that is most vulnerable to being left out. Today, Xiaobian teaches you how to self-test tires.
1. hole
Is your car stuck on a tire? If so how long ago is it? In fact, for tires that have been filled for a long time, even if they are used for the time being, it will be much less tolerant under extreme loads. In addition, if more than three holes have been drilled on the same tire, we It is still recommended that you replace it as soon as possible.
2. Drum kit
When a car drives through pits, obstacles, and curbs at high speeds, the tires will be severely deformed under a large impact force, and the internal pressure will increase instantaneously. This direct result is that the sidewall cord breaks and causes a bulge. . In addition, under the same impact force, low flat ratio tires are more likely to cause sidewall bulges than high flat tires. Tyres that have already experienced bulging must be replaced immediately, otherwise there is a risk of puncture.
3. Pattern
In general, the normal use of household cars can be replaced every 60,000 kilometers or two years, but tires with severe pattern wear should be replaced sooner. The fast repair shop now has a pattern wear ruler, the owner can buy one, at any time to detect their pattern of tire wear. In addition, the increase in tread cracks is also a sign of serious aging, usually can be sprayed with some tire protection wax, there is the drive to try not to press the corrosive liquid.
4. Air pressure
Most of today's family cars use tubeless radial tires. The front wheels sometimes look awkward but the visual inspection is inaccurate for the front-wheel drive because the important components such as the engine and the transmission are pressed on the front. , must use a dedicated tire pressure gauge measurement. In general, the pressure of the front wheels is between 2.0 Pa and 2.2 Pa. (Because the use and design of each car are different, so it is best to refer to the manufacturer's values ​​calibrated in the instruction manual.) Summer can be lower.
5. Stone
Some car owners often hear their cars make a "squeaky" noise when they are driving, but when the car is up and there is no fault, then you have to check if there are pebbles stuck in the tread. In fact, as long as you usually pump out the keys to dig out the small stones in the tread pattern, not only will the tires have a more stable brake grip, but they will also avoid tire noise.
6. Spare tire
In order for the spare tire to play a real emergency role, we must always pay attention to its maintenance. First of all, always check the spare tire pressure; Second, the spare tire should pay attention to anti-oil erosion, the spare tire is a rubber product, most afraid of all kinds of oil erosion. As soon as the tire is oiled, it will soon undergo bulking, which will greatly reduce the service life of the spare tire. In the end, the life span of the spare tire is about 4 years. Many owners mistakenly believe that the spare tire has not been used until it is new. In fact, even if the spare tire has not been used before, it must be replaced after 4 years. Otherwise, the spare tire becomes a waste tire. .
