Abstract:

PURPOSE: To prevent abnormal early abrasion by arranging a belt layer on the crown part of a radial carcass extending between sidewalls so as to reinforce them, providing treading parts separated one another axially by a wide- width ring groove, and forming a rim on an arc of a single curvature radius on the transversal face of a tread part.
CONSTITUTION: A tire 1 is so formed that a tread part 3 cylindrically extending across a pair of sidewalls 2 stretches troidally, a carcass 4 extends through a range of the sidewalls 2 and the tread part 3, and a belt layer 5 extends over the whole width of the tread part 3 on the crown part of the carcass 4 so as to reinforce them. The tread part 3 which is composed of a ring groove 8 continuously extending in the circumferential direction and a plurality of treading parts 9 separated one another axially, a pair of treading parts 9 are divided symmetrically about the equator face 0, a rim Cs on left/right treading parts is so formed as actually accorded with an arc CT of a single curvature radius RT, and the side end part on the equator face 0 of the treading parts 9 stretches to the ring groove 8 in a small curve of chamfer.
