ABSTRACT:
In a pneumatic radial tire for motocross, since only the central portion of the tread is in contact with a ground in the ordinary travel, a peculiar stress is generated at one end of the belt layer due to the directional relationship between the inclination direction of the outermost belt layer and the tire rotational direction, thus resulting in cracks in the outermost belt. To overcome this problem, the tire is covered with an auxiliary layer of textile cords arranged perpendicular to the belt outer layer cords on one side of the belt where compressive stress is produced, in order to reinforce the belt.
