Retread tire identification method 1: observe the pattern color and luster of the tire
From the grain point of view, under normal circumstances, because the processing of inferior retreaded tires is very non-standardized, the groove is relatively shallow. In terms of color, inferior retreaded tires look brightly colored and shiny, while regular ones are relatively dark.
Retread tire identification method two: observe the lap joint of the tread and sidewall
First of all, look at the sidewall, whether all kinds of labels are complete, each tire manufacturer has a forum pattern code mark, see whether the pattern code corresponds to the tire pattern. Secondly, look at whether the tread and carcass junction at the shoulder of the tire are smoothly combined, retreaded tires are homemade tread fitted to the old carcass, the lap between the tread and the sidewall is not as smooth as the new tire, and there are joint marks on the side of the tire.
Picket tire identification method three: tire marking
The brand tires produced by regular manufacturers have some protruding marks on the tires, indicating the model and performance of the tires, the expiration date is printed on the inside, and the wear marks in the tread anti-skid groove are clearly visible. Generally, the logos of retreaded tires are mostly re-affixed, and scratching these signs with your fingernails must be retreaded tires.
At the same time, each qualified new tire will have a special wear mark after leaving the factory, and generally TWI will be printed on the outside of the tire. Or the logo of the small triangle, generally reaching this mark indicates that the tire wear is more serious, can not be used, must be scrapped.
The refurbished inferior tire logo is affixed by the workshop itself, so it can also be identified by grabbing the logo with your hand.
In addition, you can also hold both sides of the tire, and inferior retreaded tires are softer.
