A radial tyre for reducing rolling noise includes a tread with a contact part located at a radially outer position to make contact with the road, two inextensible beads, two sidewalls connecting the beads to the tread, a carcass reinforcement, a belt arranged circumferentially between the radially outer part of the tread and the carcass reinforcement, and an inner crown layer located at a radially inner position. A formulation of the inner crown layer is different from a formulation of the contact part of the tread, and includes: 50 to 100 phr (parts by weight per hundred parts of elastomer) of a copolymer based on styrene and butadiene with a glass transition temperature of greater than -10° C., a reinforcing filler, and a crosslinking system.
