① Will look at the production date of the tires and also be anti-counterfeiting
Rubber products have a service life, that is, a shelf life. Like a car door sealing strip, cracks and poor sealing will occur after a long time of use.
As a rubber product, tires also have a shelf life, generally 4-5 years. After the tire is out of warranty, aging, cracking, and surface hardening will occur, which will affect the safety of driving.
When we buy tires, we look at the production date, but we can’t believe it completely. Some unscrupulous merchants used tools to modify the production date markings on tires and sold stock tires as new tires. This kind of tire mainly depends on whether the marked piece of the tire is a whole with the tire, whether there are seams or uneven edges, illegal traders mainly polish off the original production date and paste the new production date to achieve the purpose of retreading. .
② Pay attention to the installation direction and the inner and outer sides when installing the tire
Car owners will inevitably encounter situations such as tire punctures and new tires when they are used in the car. At this time, they need to remove the tires and remove the tires from the wheel hubs. However, when you install a good tire on the wheel hub, it may be upset. There will be a mark on the outside of the tire, indicating that this side should be installed to the outside.
③ The lightest point on the tire
I believe most car owners don’t know the lightest point on the tires. As a rubber product, the mass distribution of tires cannot be completely uniform. Therefore, the manufacturer will put a logo on the lightest point on the tire, and this lightest point generally corresponds to the valve on the outline. Because the contour is installed with the valve, this position has the greatest quality. The lightest point of the two tires corresponds to the most important point of the contour to balance it. The lightest point of a tire is generally marked with a yellow dot. The lightest point of the tire can also correspond to the counterweight added during dynamic balancing to achieve balance.
④ The maximum vibration point of the tire
The maximum vibration point of the tire marks the maximum point of the tire longitudinal rigidity. When the tire rotates one circle, the point of maximum vibration is at the position marked by the maximum vibration point. This phenomenon is called RFV. When the RFV is too large, the driver will feel the vibration in the car, which affects the comfort. However, consumers do not have to worry about the RFV logo on the tires of their cars. This point indicates that the manufacturer has tested the vibration points. This logo is not of great significance to consumers.
I hope you can avoid buying retreaded tires when you buy tires through this article. When installing the tires, pay attention to the lightest point corresponding to the counterweight or valve on the contour, and install the outer side of the tire outwards. This can increase the safety of driving.
