Abstract: An All Terrain Vehicle Tire (10) for the drive axle positions has a tread (12) having three circumferentially continuous channels (61 62, 63). Two of the channels (62, 63) divide the elongated lugs (40, 42) into an axially inner portion (40A, 42A) and an axially outer portion (40B, 42B). The channels (61, 62, 63) and soil discharge channels (60) between elongated lugs (40, 42) facilitate mud cleaning of the tread (12).
