Retreading is a technique used to replace the tread of a reusable used tire.
After inspection, used tires considered reusable will be scraped and brushed in order to remove the old tread.
Then, the removed materials (e.g. tread, side support pieces) are replaced with a new rubber tread during the bonding process. A last curing step engraves the forms required for adherence and the bonding of the different elements of the tire.
Retreaded tires are then subjected to the same performance and safety tests as new tires before being released on the market.
Retreaded accounts for 85% of tire sales for heavy goods vehicles and 12% of tire sales for light vehicles.
