Identify a point 1: Observe the pattern color and luster of the tire From the grainy point of view, under normal circumstances, because the poor quality of retreaded tire processing is not standardized, so groove is relatively shallow. In terms of color, poor retreaded tires look bright and shiny, while the regular retreads are relatively dark. Identifying point two: Observing the overlapping parts of tread and sidewall First of all, look at the side of the tire, the various labels are complete, the tire manufacturers have a forum pattern code mark to see whether the pattern code corresponds with the tire pattern. Next, look at whether the joint between the tread and the carcass of the tire shoulder is smooth, and the retreaded tires are self-made treads that are attached to the old carcass. The lap joint between the tread and the sidewall is not as good as the new tire. There are binding marks on the sides. Discrimination point three: tire mark Brand tires produced by regular manufacturers have some prominent marks on the tires, indicating the type and performance of the tires, the date of durability on the inside, and the wear marks in the anti-skid grooves of the tread. Most of the signs of retreading tires are usually re-attached. When these signs are scratched with nails, they must be retreaded. At the same time, each qualified new tire will have a special wear logo after leaving the factory. Generally, the outside of the tire will be printed with the TWI, or the logo of the small triangle. Generally speaking, this mark indicates that the tire is seriously worn out and cannot be used. It must be scrapped. The refurbished inferior tire mark is affixed by the workshop itself, so the hand-held mark can also be identified. In addition, you can also hold the tire on both sides, poor quality retreaded tires are relatively soft. Owners understand the method of tire identification, they must also pay attention to the following points: First of all, you cannot blindly save money and go to a roadside shop with no qualification to replace the retreaded tire. Second, at present, there are very few refurbishment of passenger car tires in China, and the purchase of car tires that are particularly cheap and refurbished is considered to be prudent. Some businesses have to pay attention to the fact that retreaded tires are sold to consumers in the name of “nine new tires†which are not worn out for a long time. Sifting Machine
