• 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,
• wherein the belt:
• is arranged circumferentially between the tread and the carcass reinforcement,
• includes a plurality of cross-superposed belt plies, and
• is provided with metallic reinforcements arranged parallel to each other within a ply, but crossed from one ply to another at an angle of between 10° and 45° relative to the median circumferential plane, the metallic reinforcements being coated with a belt coating rubber, and
• wherein the belt coating rubber is formed of at least a rubber composition that includes 50 to 100 phr of a copolymer based on styrene and butadiene with a glass transition temperature of greater than −40° C., a reinforcing filler, and a crosslinking system.
