Abstract:
Tire (1) for a heavy vehicle of construction plant type with tread (2) comprising raised elements (3), separated by grooves (4), extending radially outwards from a bottom surface (5) as far as a contact face (6) over a height (H) and comprising base compound (9) and coating compound (10). Coating compound (10) has a constant maximum thickness (emax), at the contact face (6) of each raised element (3), at most equal to 0.15 H, the coating compound (10) has a constant minimum thickness (emin), at each groove bottom (8), at least equal to 0.04 H, and the elongation at break at 23° C. AR2 of the coating compound (10) is at least equal to 1.05 times the elongation at break of 23° C. AR1 of the base compound (9).
