Abstract
A tire component is disclosed that is made of a thermoplastic composition that is based upon a cross-linkable composition. The composition includes, per 100 parts by weight of the thermoplastic elastomer, 100 phr of a thermoplastic elastomer, wherein the thermoplastic elastomer is a block copolymer that comprises an elastomer block and a hard thermoplastic block. The elastomer block is a diene elastomer and the hard thermoplastic block has a glass transition temperature greater than 80° C. The composition further includes a reinforcing filler and a curing system. In particular embodiments the reinforcing filler may be carbon black, silica or combinations thereof.
