Abstract
A tire tread (20) comprises four circumferentially extending grooves (1-4) dividing the tread into five continuous ribs (10-14) of elastomeric material. The edges of the grooves, which separate the different ribs from each other are constituted by zig-zag shaped repetitive design units (5-8;35-38). The repetitive design units on either side of the grooves (1-4) extend in circumferentially opposite directions and have each four legs, a first (5;35) and third (7;37) short leg alternating with a second (6;36) and fourth (8;38) long leg. The ribs include series of deep (40-42, 43-45) and shallow (50-52, 53-55) sipes as well as deep (48, 49) cuts.
