摘要： A heavy duty tire has a tread portion 2 which is divided into five inner, intermediate and outer rib-like land portions R1, R2, R2, R3 and R3. The inner rib-like land portion R1 is virtudally divided into half regions R1a and R1a on each side of a tire equator. The intermediate rib-like land portions R2 and R3 are virtually divided into tire equator-side half regions R2c and R3c, and into ground-contact edge-side half regions R2e and R3e. In a regular ground-contact state in which a normal load is applied, when total sums of ground-contact load applied to the half regions R1a, R2c, R2e, R3c and R3e are defined as P1a, P2c, P2e, P3c and P3e, P2c/P1a is set to 0.9 to 1.05, P2e/P2c is set to 0.75 to 1.0, P3c/P2e is set to 0.9 to 1.2, and P3e/P3c is set to 0.8 to 1.1.

摘要： A standard grounding surface shape F0 becomes a maximum grounding length Lc at a tire equator C and becomes a shortest grounding length Lm between the tire equator C and a grounding edge TE. The shortest grounding length Lm is located in a region away from the tire equator C by a distance of 0.5 to 0.9 times of a tread half width TW. A rubber thickness t1 between the carcass cord and the belt cord is gradually increased outward in the axial direction of the tire from the tire equator, and the rubber thickness t1 in a half width position Q which is away from the tire equator by a distance of 0.55 times of the tread half width TW is set to 0.5 to 3.0 mm. A ratio t2q/t2c between a tread entire thickness t2c in the half width position Q and a tread entire thickness t2c in the tire equator is set to 1.01±0.05.

摘要： A radial tire for heavy duty vehicles having a steel belt layer with triangular structure which is composed of at least three belt plies of steel belt disposed on a carcass, and a middle layer which contains cords of aromatic polyamide fibers which is laid between first belt ply and second belt ply viewed from tread surface side among the belt plies.The middle layer has skirts which are folded over from a main portion of the middle layer and laid between the first and second belt plies so as to wrap around each axial outer end of the first belt ply.The cords of the first belt play and the cords of the second belt ply cross each other at an angle of from 10 to 30 deg. against the tire equator, and the cords of the middle layer slant in the same direction as that of first belt ply at an angle of 3 deg. or less against that of first belt ply.
