| abstract |
The present invention relates to a tyre for the wheels of vehicles, in particular motor vehicles, characterized by a tread comprising 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. Said tread is characterized by 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. |
