Was asbestos used in the manufacturing of tires?

Asbestos was never directly incorporated into tires. However, the manufacturing of tires involves the movement of hot materials through pipes, and those pipes may have been insulated with asbestos containing materials in some factories.

Ingredients to make tires are: Fabric (steel, nylon, aramid fiber, rayon, fiberglass, or polyester), rubber, reinforcing chemicals, anti-degradants, adhesion promoter, curatives
