For a car, not only are there only three large parts, but the tires in the car are also a very critical spare part. It is the only place where the car has contact with the road surface, and it plays an extremely important role in the safety factor and comfort of everyone driving. If the tire is punctured, the adverse consequences are unimaginable, and according to the survey, the fatality rate of the puncture is 100% when the speed exceeds 160km/h. But before the tire burst, everything was for the sake of it. Grasping this omen can reasonably reduce the chance of puncture and reasonably reduce the damage caused by puncture.
1. Raised bag on the tire: The tire is not a pure plastic material, it also includes many steel wires called cord cloth, and when the steel wire is broken, the bag will also rise with it, and the tire wall of the part will become thinner and thinner, the compressive strength will be greatly weakened, and in the case of a strong impact again, it is easy to completely burst the tire from that position.
2. The tire pattern is more serious, the tire thickness is less than 1.6mm: the new tire or its tire pattern is shorter, the friction and wear of the tire is more obvious at this time, and the friction and drainage ability at this moment are very good. And as the mileage increases, the tires will be slowly damaged and the tread lines will become shallower and shallower. In addition, there is a proven way to investigate the thickness of the tire pattern: marking lines. In the case of newer or less damaged, the tread line is not obvious, only when the tread is damaged to a certain extent, the tread will appear, the more exposed the birthmark, the more severe the wear of the placenta. If the tread depth has long been less than 1.6mm, it means that the tire has been worn for a long time, and the tire at this time has been damaged very seriously, and the tire should be replaced in time, otherwise the tire puncture will occur at any time.
3. The tire wall has cracks: there are cracks on the surface of the tires. This kind of thing can be divided into two categories, one is the tire is some sharp protrusions on the ground or scratched by dirt and cracks, and the other is that the use of car tires has been a long time, in the wind and sun and rain continue to age, cracks, the life of the tire is reduced, if you drive on some of the more uneven ground, it is also very likely to produce a flat tire.
4. Tire pressure is unstable: Only when the tire pressure is at the standard value, the tire can work stably, to ensure the ride comfort and its safety factor, the tire pressure is too high, the tire digestion is a little hard, the digestion and absorption of the impact force will be weakened, and after the temperature rises, the internal standard air pressure will be further increased, and it is easy to produce a flat tire. During this period, the tire pressure is too low to be successful, and the deformation of the tire will also cause damage to it, so it is easy to cause tire puncture. The tire pressure must be maintained in accordance with the manufacturer's markings to meet the standard values, if it is not clear, the tire pressure on the B pillar of the main driver of the vehicle can be referred to. If the tire pressure changes frequently, and the flutter and vibration that are different from the usual driving conditions occur, it is necessary to go to the after-sales service inspection.
Tires for everyone's safe and civilized driving is very critical, must be regular maintenance and replacement, especially now almost to the Spring Festival, many friends who buy a car are likely to drive home from a distance, but also to care about the condition of the tires, before each drive, use 1-2 minutes to check their tires to see if there is such a situation, if it is, to remain alert, immediately replace the spare tires!
