Abstract: A heavy truck tire tread (2) having a longitudinal direction (LgD), a lateral direction (LtD), a tread depth direction (TdD), a ground contact surface (CS) and a pair of opposing tread shoulders (3, 4) spaced apart along the lateral direction is provided. The tread has a shoulder zone (SZ, SZ′) adjacent each tread shoulder of the pair of opposing tread shoulders, the shoulder zones consisting of blocks (5, 6) adjacent to each other along the longitudinal direction and separated by lateral grooves (7, 8). A center zone (CZ) is defined between the shoulder zones. The center zone is decoupled from both shoulder zones by at least one longitudinal sipe (11) or groove, and each lateral groove (7) in a shoulder zone (SZ) is directly connected to an opposite lateral groove (8) in the opposite shoulder zone (SZ′) by a lateral sipe (10) of the center rib.

Abstract: Disclosed herein is a tread for a tire. The tread includes at least one elongate block of rubbery material of width W and length L with L>>W. This elongate block extends in a circumferential direction (X) when the tread is mounted on the tire. The elongate block includes a contact surface intended to come into contact with the ground and a first lateral wall and a second lateral wall delimiting this contact surface. The elongate block includes a plurality of sipes opening onto the contact surface of the elongate block, with each sine extending in an oblique direction opening onto the first lateral wall and onto the second lateral wall. The sipes are distributed over the contact surface of the block in such a way that when one sipe reaches the second lateral wall another sipe starts out from the first lateral wall, at a same circumferential level (N) on the elongate block. With the sipes delimiting sub-blocks in the elongate block, at least two of these sub-blocks are configured differently in the tread.
