Abstract
A vehicle tire (10) has a tread (20) with a plurality of ribs (30,31,32) extending circumferentially about the tread. The ribs each have a pair of lateral edges (48,49;60,61) which comprise edge segments placed end to end to present a zigzag configuration. Each rib has grooves (37,38;39,40) therein which intersect the lateral edges of the respective rib and have varying depths at said lateral edges. Preferably, the tread has an all-season configuration.
