They are REMOLDED tires, which is a type of RETREAD. This means that a recycled tire casing went through the remolding process and has received a new life cycle. Remolded tires are the closest to new tires among RETREADED models. However, the tire is still not a new tire, as remolding is a RETREADING method. They do not just get a new tread area glued onto them, they receive a new sidewall and tread area, which is then cured and shaped into the desired tread pattern. These tires are DOT approved and they are guaranteed to last and to perform as well as new tires do. These tires are safer than regular retreaded models and perform as safely and successfully as new tires do. In this manner, Insa Turbo recycles old tires and contributes to lowering their carbon footprint to help save the environment.
