What are the common problems with car tires?
Tire pressure not only directly affects the life of the tire, but also closely related to traffic safety, but how much suitable for tire pressure, but there are a lot of argument. In fact, each car has a clear pressure regulations, the standard value of the vehicle tires in the cold state of the measured pressure prevail. But because many of the owners of the tires are hot before the gas, so check the pressure will be higher than the actual value, if at this time by the standard air pressure, the tire may be in the low pressure after the state, so many The refueling store will be slightly higher than the standard value when the owner is filling. But the number of high is entirely determined by the experience, so the lack of accuracy of the value. Therefore, when the tire is hot, try to make the tire in a cold state, the standard pressure should also be measured in the case of tire cooling test. If the owner thinks that the temperature of the tire is high, the pressure of the tire should be slightly lower than the standard value. The reason is that it avoids the risk of tire puncture when the air is inflated and the tire is too high. In fact, almost all of the tire traders will not advocate the owner to do so. Because the tire pressure decreases, the tire and the ground contact area increases, will cause the tire to heat up too fast, but rather easily lead to puncture. In addition, the tire pressure is too low there are many negative effects, such as: the tread on both sides of the normal wear and tear, to increase the amount of sidewall deformation, easy to damage the sidewall and so on.
Know the tire wear mark "△" pattern depth generally can not be less than 1.6mm At present, many owners do not know the extent of the tire tread to replace the tire, but do not know the importance of pattern on traffic safety. Research shows that the tread pattern is too shallow, in addition to poor drainage, the crown of the heat can not be discharged in a timely manner, so that the tire temperature rise, emergency braking, it is easy to scratch the crown rubber and lead to puncture; shallow. Especially easy to be hard to pierce the tread, causing the accident. So, what kind of pattern should be grinding to the extent of it? Under normal circumstances, every tire on every 60 degrees in its sidewall has a small "△" symbol, a total of six small "△" (Michelin tires are small snow standard), in the small "△" symbol In front of the crown part, the pattern is engraved with the residual depth limit of the pattern. When the pattern wears to this residual depth limit, the tire should be replaced and should not be used. Experiments show that the tire tread depth of the general can not be less than 1.6mm, otherwise, both the tire driving force or braking performance should be greatly reduced, and encountered waterway, there will be "water taxiing" phenomenon.
