摘要： A tyre for wheels of vehicles, in particular motor vehicles, is described. The tyre has a tread with at least one copolymer of (iso-styrene/trans-butadiene): diene-terminated copolymers. The tread has less sensitivity to the effects of temperature, with less weakness, better consistancy of performances, and improved characteristics in terms of grip and/or resistance to laceration.

摘要： A tyre for wheels of vehicles, in particular motor vehicles, is described. The tyre has a tread with at least one iso-styrene/trans-butadiene elastomeric copolymer with a styrene content higher than 30% by weight with respect to the total weight of copolymer and a molecular weight higher than 500,000. The tread has improved dynamic-mechanical behaviour at high temperatures, with higher dynamic modulus and hysteresis values, and at the same time better properties at break, optimum elasticity at low temperature and higher abrasion resistance.
