Abstract
A pneumatic tire having a tread portion comprises a mid-circumferential zig-zag rib and a plurality of blocks located in the edge portions of the tread between adjacent peaks of the zig-zag rib. The zig-zag rib has amplitude of between 60-70% of the tread width and has sied faces thereon that have an exposed length of at least 40% of the tread width. By varying the width of the grooves, between the blocks and the rib, on one rotational directional side of the rib from the width of the grooves on the other rotational directional side of the rib, it is possible for the tire to have different traction grips for each rotational direction.
