【Car owner's family car knowledge]The continuous increase in the cost of using a car is forcing people to not let go of any details of saving expenses. Tires are actually a cost-intensive consumable in the process of using a car. Four tires are worth thousands of yuan. If improper use leads to abnormal wear and tear, it will also be a test for the owner's wallet. How to reduce tire wear and maximize the service life of tires is the knowledge that car owners must master. Good and skilled driving skills can effectively reduce tire wear, prolong tire life, and improve driving safety. The following will focus on the maintenance knowledge of tires for you.
Insufficient or too high tire pressure can easily lead to a puncture
"You must add air to the tires on high-speed." Many riders believe that the car must have the "strength" to run at high speed when the air is full on high-speed. "But in fact, this kind of thinking is wrong. Dongfeng Fengshen 4S The store staff introduced that the tire pressure is too high, which will reduce the contact area between the tire and the ground. At this time, the pressure on the tire is relatively increased, and the grip of the tire will be affected. In addition, when the vehicle passes through a ditch or a bumpy road, the There is not enough space in the tire to absorb the vibration, which will not only affect the driving stability and ride comfort, but also increase the impact force on the suspension system, which will also bring harm.

In addition, when the vehicle passes through a ditch or a bumpy road, the There is not enough space in the tire to absorb the vibration, which will not only affect the driving stability and ride comfort, but also increase the impact force on the suspension system, which will also bring harm.
When the tire pressure is lower than the standard value, the wear of the tire shoulder increases sharply; when the tire pressure is higher than the standard value, due to the reduction of the tire contact area and the increase of the unit pressure, the wear of the middle of the tire tread increases, and the rigidity of the tire is increased at the same time. , so that the dynamic load on the wheel increases, and the carcass is prone to burst.
Do not start too hard, avoid frequent use of brakes and emergency braking, so as not to accelerate tread wear due to tire and ground drag; Speed and pay attention to the road surface, pedestrians, and vehicle dynamics, prepare for braking, reduce frequent braking, and avoid emergency braking, thereby reducing tire wear; when faced with unavoidable broken glass or other foreign objects, slow down and pass. Do not brake hard, because the pressure build-up caused by sudden braking makes it easier for glass fragments and foreign objects to penetrate the tires.
Check the tread for cracks and beware of puncture at high speed
"My tire was punctured by glass on the side. Is there any problem with running at high speed after the tire is repaired?" a car owner asked. According to the staff of the 4S shop, if there is an injury on the side of the tire, the insurance factor will not be guaranteed, because there is basically no steel wire on the side of the tire, the sidewall is very thin, and the tire is prone to blowout at high speed. Regularly check the tire surface for cracks, deformation and other defects. The tread groove of the tire gradually becomes shallower due to driving wear. If it is ground flat, it will lose its drainage and anti-skid effects, and the performance of the car will be greatly reduced. The seemingly small cracks are the hidden danger of tire blowout during high-speed driving. Pay attention to remove the small stones in the groove in time.
Avoid parking your vehicle on rough, pointed or sharp-edged pavements. Do not park the vehicle near or in contact with petroleum products, acids and other materials that affect the deterioration of rubber. The driver should not turn the steering wheel after parking, as doing so will accelerate tire wear. Tires are prone to overheating and increased air pressure when driving for a long time in summer or at high speeds. At this time, it should be stopped to dissipate heat, and it is strictly forbidden to deflate the pressure or splash water to cool down, so as to prevent the abnormal aging of the tread rubber.
It is better to pay attention to the road when driving than to maintain a good habit
According to the staff of the towering auto repair, when driving in the road maintenance and construction area, the method of selecting the road surface at a low speed should be used to avoid excessive impact on the tires, or even being stabbed or scratched; when driving on uneven roads, the first choice is to choose the road surface. On the road surface, reduce the collision between the tire and the road surface, and avoid damage to the machine parts and tires; secondly, slow down to avoid bumps and strong vibrations of the tires; when passing through muddy areas, you should choose a firmer and non-slippery place to pass, so as to avoid the tires sinking and the original The tires and sidewalls are severely cut and scratched due to the idling of the ground and the intense heat generation.
Turning of the vehicle should be based on the condition of the curved road and the turning radius. Generally, it is necessary to decelerate properly to avoid the acceleration of unilateral tire wear due to the action of inertial force and centrifugal force. When the vehicle goes downhill, the appropriate speed should be controlled according to the size, length and road surface conditions of the slope. In this way, emergency braking can be avoided or less used, and tire wear can be reduced; when the vehicle stops on the way and stops at the station, it is necessary to develop the habit of sliding safely. In the maintenance and use of tires, don't forget the most important tire - the spare tire. The spare tire is equipped by the manufacturer, but it is often forgotten by the owner and lacks maintenance. It is recommended that car owners check the spare tire regularly every 3 months, and inflate it if necessary, so as not to find it is flat when it is needed.
