After Professional RV Modification, You Should Master the Practical Skills to Distinguish Inferior R

Professional RV modification difference point 1: Observe the color of the tire tread

From the perspective of the grain, the grain grooves of low-quality retreaded tires are relatively shallow due to irregular processing. In terms of color, inferior retreaded tires look bright and shiny, while ordinary tires are relatively dark.

Professional RV modification difference point 2: Observe the overlap between the tread and the sidewall

First, check whether there are various marks on the sidewall of the tire. Each tire manufacturer has a forum pattern code mark to see if the pattern code corresponds to the tire pattern. Secondly, check whether the joint between the tread and the carcass at the shoulder is smooth. Retreaded tires are made with homemade treads that fit the old carcass. The overlap between the tread and the sidewall is not as smooth as that of new tires. There are traces of seams on the side of the tire.

Professional RV modification difference point 3: Tire marks

Branded tires produced by regular manufacturers have some obvious marks on the tires, indicating the type and performance of the tire. The warranty date is printed on the inside, and the wear marks in the tread anti-skid groove are clear. Generally speaking, the signs of retreaded tires are mostly re-pasted. If you scratch these signs with your fingernails, you will definitely be able to recognize the retreaded tires.
At the same time, every qualified brand-new tire will have special wear marks after leaving the factory. Generally, the tire will have a TWI or small triangle mark printed on the outside of the tire. Generally, reaching this mark means that the tire is severely worn and cannot be used and must be scrapped.

The logo of retreaded inferior tires is pasted by the workshop itself, so you can also identify it by grabbing the logo with your hands.
In addition, you can also clamp the sides of the tire. Inferior retreaded tires are relatively soft.

When car owners know how to identify tires, they should also pay attention to the following points:
First, you can't just save money. Go to the unqualified roadside shop to replace the retreaded tires at will.
Secondly, there are relatively few retreaded car tires at present, and you should be cautious about buying particularly cheap car tires called retreads. It should also be pointed out that some merchants sell retreaded tires to consumers in the name of "90% new tires", and these tires have not been worn for a long time.
Of course, the safer way is to buy tires from regular merchants.
