PCT No. PCT/US96/12964 Sec. 371 Date Jun. 25, 1998 Sec. 102(e) Date Jun. 25, 1998 PCT Filed Jul. 18, 1996 PCT Pub. No. WO98/03356 PCT Pub. Date Jan. 29, 1998An all terrain vehicle tire 10 has a tread 12 specifically designed for mud traction. The tread 12 has four circumferentially repeating rows 1,2,3,4 of elongated lugs 40,42, two shoulder rows 1,2 and two central rows 3,4. Adjacent the axially outer ends 45 of the lugs 42 of the central row 3,4 is a shoulder block 44. The tread 12 has soil discharge channels 60 extending axially between the lugs 40,42. Each channel 60 is open in two locations 61,62 to one or more axially aligned and circumferentially adjacent soil discharge channel 60. Preferably each location 61,62 represents about 20% of the axial arc width of a tread half. These locations 61,62 permit mud to move freely from a forward channel 60 towards a rear channel 60 and enhances tread cleaning as the tire 10 rotates.
