Every day, I see a lot of car owners. They love car care. They often spotlight their own cars. They regularly visit the 4S stores for car maintenance, but they do ignore the tires that are the most worn parts of the car. If the car's "foot" fails or is in poor condition, then no matter how good the car's performance is, it will not be reflected. So how do you check the tires and what should you watch out for when you use the tires?
As a consumable, tires need to be replaced after a period of use. First of all, the front and rear wheels of a car should be shifted diagonally every 10,000 kilometers. The family cars are basically front-wheel drive. The front wheels are both responsible for steering and are responsible for driving the vehicle. This leads to wear of the front and rear tires. The degree is not the same, and the wear of the tire is also related to the distribution of the weight of the vehicle, and the replacement of the tire can greatly help the even wear of the tire. Tires with different specifications, structures, and wear resistance have a great influence on the handling and stability of the vehicle. In addition, the tire replacement should be carried out in a professional maintenance station. After the tires are exchanged, it is best to do a four-wheel alignment. Although this is not mainly for tire maintenance, it is still very good for the entire vehicle.
Tire wear to a certain extent must be scrapped, usually when the wear marks on the tread exposed, it should be scrapped, ordinary tires in the 80,000-kilometer journey will also be scrapped. However, many people think that only pattern polishing is needed to be replaced. In fact, when the road is slippery, long-term use of tires with severely worn tires, the steering wheel and the brakes almost completely fail, and the automobile is prone to sideways deviations that cause accidents.
In the tire's use, the tire pressure is a very important indicator. It is necessary to ensure that the tire pressure is consistent with the manufacturer's required air pressure. Otherwise, regardless of whether the tire's air pressure is too high or too low, it will cause great damage to the life of the tire. If the air pressure of the tire is too high, the pattern on the center of the tread of the tire will be more worn than those on both sides. When the air pressure of the tire is too high, the contact area of ​​the tire with the ground is small, the car accelerates, and part of the tire on the ground is removed. Back to the ground will be deformed due to acceleration, and thus appear to fluctuate. In this way, not only will the tire resistance increase, it will affect the acceleration performance of the car, and it will cause steering wheel vibration and deviation. When the air pressure is too high, when it comes to nails, glass, and other sharp objects on the road surface, it is easy to get into the tire and even cause a flat tire. Excessive external pressure will also reduce the comfort of driving, and the vibration absorbed by the tire itself will become smaller, indirectly affecting the life of other components. In addition, if the tire pressure is too high, the grip will drop and the fuel consumption will increase. If the air pressure is too low, the amount of movement in various parts of the tire will increase, resulting in abnormal heating of the tire, which will reduce the function of the cord and the rubber, cause excessive friction between the delamination or breakage of the cord and the rim, and cause damage to the bead area. Abnormal wear.
As the tire pressure drops, the friction between the tire and the ground increases exponentially, the temperature of the tire rises sharply, the tire softens, and the strength decreases sharply. In this case, if the vehicle is driving at high speed, it may cause a puncture. In addition, the tire pressure is insufficient, the friction coefficient with the road surface increases, and the fuel consumption also increases. In short, in a word, if the air pressure is high, if it is low, it will not work. It must be appropriate. While you are driving, it is best to pay attention to the tires of your car. It is best to buy a household tire pressure gauge and measure it once a week. , Eliminating security risks in the bud.
In terms of tire repair, be sure to find a professional store hot, pay attention, must be hot to make up, can not glue to deal with. Otherwise, the parts inside the tire, such as the belt layer, tend to deteriorate, forming bulges and threatening the safety of driving. After repair, you can go on the highway, but be careful to install the repaired tire on the rear wheel. Of course, problems occur in the non-repairable areas such as the sidewalls, and tires must be discarded and must not be used again.
First of all, because the spare tire is used less often, it will have different wear levels with the other four tires, so the friction coefficient will be different. If the spare tire is used for a long time, it will have a brake system, steering system and Suspension system has a certain impact, but at the same time it will bring certain hidden dangers to traffic safety. Therefore, we should promptly remediate damaged tires and replace them with spare tires. In addition, pay attention to adjust the air pressure when changing the spare tire, because the spare tire air pressure and the tire is in use there is a certain number of differences, so before the replacement of the use of barometer to adjust it to normal after normal use. In addition should also do the following:
1, regular inspection of the spare tire: In daily maintenance or long-distance travel, the spare tire should be tested for wear or cracks, if worn to the mark line, then it should be replaced as soon as possible. However, if there is a small crack on the sidewall, it cannot be used to run long distances or high speeds, because the thinner tire sidewalls are prone to puncture when they are running at high speed.
2, do not put together with corrosive items: Because the main component of the tire is rubber, and rubber is most afraid of all kinds of oil erosion. Some owners often store similar oils such as lubricating oil in the trunk. When these oils touch the tires, the tires will distort to a certain degree, which will greatly reduce the service life of the tires.
3, the spare tire also has a life: Do not think that the spare tire has not been used in the trunk, you can "longevity." Maybe some owners have encountered such a similar situation, when the tire is tied or damaged When replacing with the spare tire, it was found that the spare tire had been severely aged and could not be used. This is because the tires are rubber products. If they are stored for a long time, they will be aging. The general aging period is about 4 years.
4. The spare tire should not be used for a long time: Because the spare tire is used at a low frequency and the friction coefficient with the other four tires is different, and the flat ratio, tire width or tire diameter of the non-full-sized spare tire is different from that of normal-use tires, therefore Prolonged use will have a certain impact on the vehicle's braking system, steering system and suspension system, causing hidden dangers to traffic safety, and also causing uneven friction in other tires in the same direction.
5. After the repair, it should be placed in the rear wheel: if the repaired tyre is to be used again, no matter what kind of driving method the vehicle should be placed on the rear wheel, this is because the risk coefficient after the front tyre burst is relatively higher. , so the repaired tires will be relatively safe in the rear wheels.
Summer car tires use matters needing attention
