Tire compounds with improved tear, flex fatigue, and ozone resistance

A method of producing a tire including mixing in a non-productive phase at least one elastomer with a polyamide having a melting temperature of less than 180 °C. The polyamide is allowed to heat to at least its melting temperature. During the productive phase, at least one curing agent is added to t...

More Information
Summary:A method of producing a tire including mixing in a non-productive phase at least one elastomer with a polyamide having a melting temperature of less than 180 °C. The polyamide is allowed to heat to at least its melting temperature. During the productive phase, at least one curing agent is added to the elastomeric composition. The curing agent may be a sulfur containing curing agent and/or a non-sulfur containing curing agent. The elastomeric composition may optionally include a crystalline EPDM elastomer. The resulting compositions may then be formed into a tire component which may be built into a tire and cured.
