Abstract

PURPOSE: To improve resistance to partial wear, of the title tire for a bus and the like, by forming a shoulder portion outer contour, axially outside from a specific point on a tread, in a specific negative radius of curvature so as to form a shoulder falling to a specific correcting value.
CONSTITUTION: The inner/outer contours of a mould on a tread center portion, away from a tread center CL to a point of 0.64W0.85 times the half width of a tread, is formed at a positive radius of curvature R1 having its center of curvature on the tire axis side, and the outer contour of a shoulder outside of this point is formed at a negative radius of curvature R2, 1W30 times a tread width. Furthermore, a tread shoulder portion falling correcting value H2 is set at 0.05W0.04 times the head H1 at a single tread crown radius of curvature. Hence the charge of operating internal pressure will cause the whole area of the outer contour to expand outwardly in the axial direction beyond the tread outer contour and its ground contacting shape in loading to be nearly rectangular. This constitution improve resistance to partial wear.
