A rubber composition based on at least one diene elastomer, a reinforcing filler predominantly comprising a filler covered at least partially by silica and a crosslinking system. The dispersion of the filler in the elastomeric matrix has a Z score greater than or equal to 70, and the composition is devoid of agent for coupling the filler with the elastomer.

Elastomer composition comprising a filler at least partially covered by silica

A radial tire () for a heavy vehicle of construction plant type, and more particularly, the sidewalls thereof (), arranged to minimize the temperature of the tire while guaranteeing its electrical conductivity. The tread () comprises two tread wings () and a central portion (). The bead layer (), the elastomeric coating compound of the carcass layer (), the second sidewall layer () and the tread wing () constitute a preferential conductive pathway of the electric charges between the rim and the ground when the tire is mounted on its rim and flattened on the ground.

The invention relates to a rubber composition based on at least one diene elastomer, a reinforcing filler comprising at least carbon black having a CTAB specific surface of greater than or equal to 130 m/g, a plasticizing oil and also a crosslinking system, the dispersion of the filler in the elastomeric matrix having a Z score of greater than or equal to 70.
