Care for the "feet" of automobiles teaches you six methods of tire self-inspection

    As the "foot" of a car, tyres always serve the owner silently. In fact, no matter how fast the car can run, it's no use leaving the four feet. However, such a key part is the most vulnerable to neglect. Today Yuhuan Leteng Machinery Manufacturing Co., Ltd. teaches you several methods of tire self-inspection.

    1. hole

    Has your car been tied into a tire? If so, how long ago? In fact, for a tire that has been repaired for a long time, even if it is not a problem temporarily, its endurance under extreme load will be much worse than before. In addition, if more than three holes have been pierced in the same tire, we recommend that you replace it as soon as possible.

    2. drum bags

    If the car passes through the pits, obstacles and Road teeth at high speed, the tyre will be seriously deformed under the huge impact force, and the internal pressure will increase instantaneously. The direct consequence is that the tyre side cord will break and cause bulging. In addition, under the same impact strength, the tire with low flat ratio is more likely to cause sidewall bulging than that with high flat ratio. A bulging tire must be replaced immediately, otherwise there will be a hidden danger of tire burst.

    3. patterns

    Generally speaking, the normal use of household cars can replace tires every 60,000 kilometers or two years, but for tyres with severe pattern wear, it should be replaced earlier. Now the fast repair shop has pattern wear gauge, the owner can buy one, at any time to detect their tire pattern wear condition. In addition, the increase of tread cracks is also a symbol of serious aging. Usually, some tire wax can be properly sprayed, and it is necessary not to press into corrosive liquids when driving.

    4. air pressure

    Nowadays, most domestic cars use tubeless tyres. For the front-wheel, the engine, transmission and other important driving parts are pressed in the front, so the front wheel sometimes looks a little flat, but the visual measurement is inaccurate, so it must be measured with a special tyre pressure gauge. Generally speaking, the air pressure of the front wheel is between 2.0 Pa and 2.2 Pa. (Because the use and design of each vehicle are different, it is better to refer to the factory value calibrated in the use manual) Summer can be appropriately low.

    5. stones

    Some car owners often hear their car whisper when they are driving, but the car doesn't break down when they use it. Then you need to check if there are small stones stuck in the tread pattern. In fact, as long as you use the key to dig out these small stones in tread pattern, it will not only make the tire brake grip more stable, but also avoid tire noise.

    6. spare tire

    In order to spare tires play a real emergency role, we should pay attention to its maintenance in peacetime. First of all, we should check the air pressure of spare tyres frequently. Secondly, we should pay attention to oil corrosion prevention. The spare tyres are rubber products, most afraid of the erosion of various oil products.  When the tire is greased, it will be corroded soon, which will greatly reduce the service life of the spare tire. Finally, the life span of spare tires is about 4 years. Many owners mistakenly believe that spare tires are always new when they are not used. In fact, after 4 years, even if spare tires have not been used once, they should be replaced, otherwise they will become aborted tires.
