A directional tire (10) having lateral grooves (15,16) arranged in substantially "V" shaped configurations around the tire. The lateral grooves (15,16) on each side of the mid-circumferential plane (M-M) form a series of circumferentially spaced lands (25,26) respectively therebetween, each of which extends from a mid-circumferential portion of the tire to the respective edge of the tread (12 or 13). Each land (25,26) has a first face (27) directed in one rotational direction and a second face (28) directed in the other rotational direction. In order to modify the directional properties of the tire one of said faces, preferably the trailing face (28) in normal use, is broken by axially extending grooves (31,32 and 33). |
