摘要 |
In order to improve the resistance to separation between the ends of the working plies (31 to 34) of a crown reinforcement (3) and between the edges of said reinforcement (3) and the radial carcass reinforcement (2), the said plies have axial widths which are different from each other, and at least two of the widths are greater than the axial distance (L) between the median axes (XX') of the two lateral grooves (6) closest to the edges of the tread (1) and defining lateral regions (7) where the tread (1) has a meridian profile (8) radially recessed with respect to the meridian profile (9) of the geometrical envelope of its median zone.
