PURPOSE:To improve running performance both on a general road and a soft road by regulating the outer profile of a tire and respectively forming the block patterns of specific form on a tread part and a buttress part. CONSTITUTION:On a tire 1, a carcass 9 is provided while being consisting of a cross ply of organic fiber cord which is folded around the circumference of a bead core 7 on a bead part 6 through a side wall 5 including a tread part 2 and a buttress part 3 and inclined at an angle of 30 to 80 deg. with respect to the rotating direction of the tire. A compression H/OW which is the ratio of the maximum width OW to the section height H of the tire combined with a rim and staying in a standard state with normal internal pressure applied therein is set to 45 to 90%. Further, in the tread part 2, respective block trains UC, US, UM consisting of central blocks BC, shoulder blocks BS and intermediate blocks BM having mutually special relations are formed. |
