摘要： A radial tyre for a motor vehicle includes a crown, two beads, a crown reinforcement, and an inner crown layer. A tread of the crown includes a contact part located at a radially outer position and intended to make contact with a road surface. The inner crown layer is located at a radially inner position and is formed of an elastomeric material having a different formulation from that of the contact part of the tread. The inner crown layer is arranged circumferentially between the contact part of the tread and the crown reinforcement or between the crown reinforcement and a carcass reinforcement, and functions to reduce rolling noises of the tyre. The elastomeric material includes a rubber composition with at least: 50 to 100 phr of a copolymer based on styrene and butadiene with a Tg greater than −40° C., a reinforcing filler, a hydrocarbon-based plasticizing resin, and a crosslinking system.

摘要： A vehicle tire includes a tread formed of a heat-expandable rubber composition when in an unvulcanized state. The composition includes: from 50 to 100 phr of a copolymer based on styrene and butadiene; optionally from 0 to 50 phr of another diene elastomer, such as a polybutadiene or natural rubber; more than 50 phr of a reinforcing filler, such as silica and/or carbon black; between 5 and 25 phr of a blowing agent, such as an azodicarbonamide compound; and between 5 and 25 phr of a heat-fusible compound having a melting point between 70° C. and 150° C., such as urea or a heat-fusible urea derivative. A total content of the blowing agent and the heat-fusible compound is greater than 15 phr. Use of the composition enables, after the tire is vulcanized, a significant reduction in noise emitted by the tire during running.
