Knowledge about tires
Generally, it is better to change the car tire once every 3-5 years or 60000-80000 kilometers. The validity period of ordinary tires is 5 years after production. If the tires are really used for 7 or 8 years, it is recommended to replace them in time, otherwise there is a risk of tire burst. Because the tire is a rubber product, its characteristic is that it will age with the passage of time, mainly manifested in surface hardening, followed by turtle cracks.
Aging does not happen without using tires, but it takes too long to place or use. Especially if the replacement cycle has been exceeded, it must be checked thoroughly before use. After all, safety is no small matter. The tire has been used for 7 or 8 years, which has obviously exceeded the replacement cycle. It needs a comprehensive inspection of the tire before it can continue to be used.
For the service life of tires, even if Michelin tires and continental tires claim that their tires can be used for more than 10 years, they also suggest that after 5 years, a comprehensive inspection should be conducted by professionals every year. Nissan and Mercedes Benz remind car owners that no matter how worn the tires are, they should replace them six years after they leave the factory. All these show that in any case, tires that exceed the service life can not continue to be used and need to be replaced in time.
However, it is not only the need to replace the tire after a long time, but also the need to replace the tire in time if the tire is worn to a certain period, the sidewall bulges, the tire is pierced with large holes or the number of repairs is too many.
The most direct judgment method is to observe the wear degree of tires. Almost every tire will have a wear mark. Generally, the wear mark height of car tires is 1.6mm (this height is also the legal minimum groove depth of tires), and the wear mark height of truck tires is 2.4mm. If it is found that the wear mark is the same as the tread, it means that the tire has been almost worn and should be replaced in time.
It can be said that the phenomenon of nail puncture in the tire is very common, but if the puncture hole is relatively large or the repair times are too many, it will directly affect the driving safety. At this time, it can not be solved by mending the tire. Especially when driving at high speed, the pressure of the tire is quite high. If driving for a long time, there is a certain probability of tire burst. Therefore, we must not have a fluke mentality, and we should replace it in time.
