Identification point one: Observe the pattern color and gloss of the tire
From the perspective of the texture, in general, because the processing of inferior retread tires is very irregular, the grooves are relatively shallow. In terms of color, inferior retread tires look bright in color and shiny, while the regular ones are relatively dark.

Identification point two: Observe the joint between the tread and the sidewall
First look at the sidewall, whether the various signs are complete, and each tire manufacturer has a forum pattern code mark to see if the pattern code corresponds to the tire pattern. Secondly, look at whether the joint between the tread and the carcass at the shoulders is smooth. The retreaded tires are all self-made treads attached to the old carcass. The overlap between the tread and the sidewalls is not as smooth and round as the new tires. There are bonding marks on the side.


Identification point three: tire mark
Brand tires produced by regular manufacturers have some raised signs on the tires, indicating the type and performance of the tires, the expiration date is printed on the inside, and the wear marks in the tread anti-skid grooves are clearly visible. Generally, the signs of retreaded tires are mostly re-attached. If you scratch these signs with your nails, the retreaded tires must be removed.
At the same time, each qualified new tire will have a special wear mark after leaving the factory. Generally, the outside of the tire will be printed with a TWI or a small triangle mark. Generally, reaching this mark indicates that the tire is worn out and cannot be used and must be scrapped.
The refurbished inferior tire logo is affixed by the workshop itself, so it can be distinguished by grabbing the logo by hand.
You can also hold both sides of the tire. Inferior retread tires are softer.
