Abstract
A tire (1) comprises a tread (3), a crown with a crown reinforcement (2), two sidewalls (5), two beads (4), a carcass reinforcement (6) anchored to the two beads (4) and extending from one sidewall (5) to the other, the tread comprising (a) an elastomeric matrix which comprises predominantly one or more thermoplastic elastomers comprising at least one elastomer block and at least one thermoplastic block, and (b) a crosslinking system based on one or more peroxides. The invention also relates to a process for preparing the tire.
Claims30
A tire comprising a tread, a crown with a crown reinforcement, two sidewalls, two beads, a carcass reinforcement anchored to the two beads and extending from one sidewall to the other,
- wherein the tread comprises:
- (a) an elastomeric matrix comprising at least 50% by weight of at least one thermoplastic elastomer comprising at least one elastomer block and at least one thermoplastic block, relative to all of the elastomers present in the elastomeric matrix of the tread,
- wherein the at least one thermoplastic elastomer is a triblock copolymer comprising thermoplastic block/elastomer block/thermoplastic block;
- and
- (b) a crosslinking system based on at least one peroxide,
- wherein the peroxide content ranges from 0.1 to 10 phr.
