Abstract

PURPOSE:To improve roadability regardless of surfaced road, muddy road, snow- covered road, etc. by integrating the tread in such a way that blocks in possession of two different kinds of standard forms having groove parts which are composed of deep grooves and shallow grooves are regularly arranged in the circumferential direction of tire. CONSTITUTION:The center block (A) is arranged at the center part of the tread, and the side block B arranged on the lateral part of the tread respectively regularly in the circumferential direction, Five to ten pieces of quasi-orthogonal angular parts (a) are formed at the center block (A), and eight to sixteen pieces of angular parts (a) formed likewise at the side block B. Besides, the tread groove parts are integrated by deep groove parts 4 and shallow groove parts 5, and the depth d of the groove parts 4 from the bottom of the shallow parts 5 is determined to be 5%-40% of the depth D of the shallow groove parts 5. Thus, tractive force can be improved on the off-road, exfoliating ability of dirt, etc. can be improved, and resistance to wear on the tire can be improved in such a way that the number of the angular parts (a) and the depth of the groove parts 4, 5 are determined.
