How to Distinguish New Tires from Retreaded Tires?
1 Answers
Differences between new tires and retreaded tires: 1. Observe by gently scratching the tire with a key: Gently scratch the tire with a key. New tires have good elasticity, and the scratch will disappear quickly; retreaded tires have poor elasticity and will leave marks. 2. Observe the joint between the tread and the sidewall: The joint of a new tire is very smooth; retreaded tires have traces of bonding at the joint. 3. Observe the tire hairs: New tires have tire hairs, which will gradually disappear after driving 5 to 10 kilometers; retreaded tires do not have tire hairs, nor can they be faked. 4. Observe the tire pattern and gloss: New tires have deep patterns and a soft gloss; retreaded tires are old tires with shallower patterns. To meet the gloss standard, a large amount of wax is applied, resulting in a shiny appearance.
