摘要：
A radial tyre for motor vehicle includes: a crown with at least a tread and a crown reinforcement or belt, two inextensible beads, two sidewalls connecting the two inextensible beads to the tread, and a carcass reinforcement passing into the two sidewalls and anchored in the two inextensible beads. The belt is positioned circumferentially between the tread and the carcass reinforcement, and includes textile or metallic reinforcers coated with a rubber composition referred to as a “belt-coating rubber.” The belt-coating rubber, which is capable of reducing the tyre's rolling noise, includes a diene elastomer and more than 50 phr of a filler of high-density particles having a density of greater than 4 g/cm3.
