TIRE COMPRISING AN ELASTOMERIC POLYMER INCLUDING A FUNCTIONAL GROUP AND CROSSLINKABLE ELASTOMERIC COMPOSITION

摘要

A tire for heavy load vehicles comprising: - a carcass structure; - a belt structure applied in a radially external position with respect to said carcass structure; - a tread band in a radially external position with respect to said belt structure; - a pair of sidewalls laterally applied on opposite sides with respect to said carcass structure; - at least one structural element selected from said tread band and said sidewalls being obtained by crosslinking a crosslinkable elastomeric composition comprising: (a) at least about 50 phr of at least one functionalized elastomeric polymer including from about 0.05% by weight to about 10% by weight, with respect to the total weight of the elastomeric polymer, of at least one functional group selected from carboxylic groups, carboxylate groups, anhydride groups, ester groups; (b) from ' about 10 phr to about 70 phr of at least one carbon black reinforcing filler; (c) less than 50% by weight relative to said carbon black reinforcing filler of an additional reinforcing filler.
