Title: HEAVY TRUCK TIRE TREAD AND HEAVY TRUCK TIRE
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.
