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.
