Concepts of cold retreading:

The low temperature is against the high hot retreading temperature. Generally, 120°C is the denatured point of rubber, over called hot retreading, blow called cold retreading. And more advanced technology allows the temperature below 100°C. Because of the high temperature produce a negative effect to the tyre, the cold retreading is more and more popular.

Precure retreading means the tread should be procured by the high-pressure vulcanizing machine separately, while the hot retreading means the tread and casing are made up with non-vulcanized rubber, so the tread pressure is far below than the cold retread technology. Therefore, wear resistance, mileage of cold retread tyre can be comparable to the new tires, and flat mould can make tread with kinds of patterns, help the users to choose the more suitable patterns. However, it will be a big expense if you change tread patterns with hot retreading technology.
