Abstract
The tire has a radial carcass reinforcement intended to equip vehicles carrying heavy loads and running at sustained speed. The tire comprises a crown reinforcement, itself capped radially with a tread joined to two beads via two sidewalls. The tread comprises at least two radially superposed layers of polymeric compound, a radially outer first layer that comes into contact with the ground and a radially inner second layer. The second layer has a composition based on at least a diene elastomer, a reinforcing filler comprising predominantly a filler covered at least partially by silica, an agent for coupling the filler with the elastomer and a crosslinking system. The dispersion of the filler in the elastomeric matrix has a Z value greater than or equal to 70.
