Abstract

Tyre tread (10) having a tread surface (11), this tread comprising at least two wearing layers, this tread being characterized in that it is provided with at least one continuous groove (2) comprising a plurality of external cavities (21) opening onto the tread surface in the as-new condition and a plurality of internal cavities (22) placed radially and completely inside the tread surface (11) in the as-new condition, the external cavities (21). having a mean depth P1, a mean length L1 and a cross-sectional area S1, the internal cavities (22) having a mean height P2, a mean length L2 and a cross-sectional area S2, these external (21) and internal (22) cavities being such that: the difference between the mean lengths of the internal cavities and of the external cavities is at most equal to 20% of the longest mean length, the difference in the mean cross-sectional areas of the internal and external cavities is at most equal to 20% of the largest mean area, each external cavity (21) of a continuous groove (2) being connected to at least two internal cavities (22) of the same groove by connecting channels (23) that provide continuity between the said internal and said external cavities, this tread further comprising a plurality of incisions (30) opening onto the tread surface of the tread in the as-new condition, each of the said incisions connecting two consecutive external cavities of one and the same groove and at least two connecting channels and at least one internal cavity.
