PURPOSE:To improve earthing properties, by a method wherein a tyre for all-terrian vehicle for running on an off road such as westland, the tyre is formed such that a tread rubber having an uneven pattern is sticked to the outer surface of a rim comprising an annular body, formed in a circular arc in cross section, and a support part coupled to a tyre rotary shaft. CONSTITUTION:A tyre 1 is formed such that a tread rubber 3, having an uneven pattern, is sticked to the surface of an annular body 4 of a rim 2 comprising the annular body 4, formed in a circular arc in cross section, and a support part 5 which extends along an equator surface and coupled to the rotary shaft of a tyre. In which case, block groups P, each consisting of 5 blocks aligned juxtaposition with each other in the direction of the width of a tread rubber 3, are circumferentially aligned at given intervals, and heights H1-H5 of the blocks are set to more than 50% of a thickness H of the tread at an equator surface C of the tyre. This constitution enables a vehicle to safely run on an off road, such as wasteland, even under sever condition, and permits improvement of braking properties, and driving properties. |
