Drum bag
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, at the same impact strength, 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.
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 earlier. The fast repair shop now has a pattern wear ruler, the owner can buy one, at any time to detect the pattern of their own 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.
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 meter measurement. In general, the pressure of the front wheel 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 value as specified in the instruction manual.) Summer can be appropriately lower.
Stone
Some owners will often hear their car make a "squeaky" noise while driving, but there is no problem with the car. At this time, you need to check if there are pebbles stuck in the tire 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.
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, bulk corrosion will occur soon, 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. .
The above is to introduce to you the common six major faults of the vehicle tires encountered the best to replace immediately, I hope to help you!
