Pneumatic Tire

摘要

This pneumatic tire (1) includes: a pair of bead cores (11, 11); a carcass layer (13) extending between the pair of bead cores (11, 11); and a belt layer (14) including a laminate of at least four belt plies (141 to 144) having steel belt cords covered with coating rubber, the belt layer being disposed on the outer side in a tire radial direction of the carcass layer (13). An inter-cord distance (Ga) between an outermost layer belt ply (fourth belt (144)) and an adjacent belt ply (third belt (143)) has a relationship such that 0.80≦Ga/φmax≦1.80 with respect to a maximum value ((max) of outer diameters (φ4, φ3) of belt cords (1441, 1431) in the outermost layer belt ply (144) and the adjacent belt ply (143).

1. A pneumatic tire comprising:
a pair of bead cores; a carcass layer extending between the pair of bead cores; and a belt layer including a laminate of at least four belt plies having steel belt cords covered with coating rubber, the belt layer being disposed on an outer side in a tire radial direction of the carcass layer; when the belt ply disposed on an outermost side in the tire radial direction is designated as an outermost layer belt ply and the belt ply disposed on an inner side in the tire radial direction of the outermost layer belt ply is designated as an adjacent belt ply, an inter-cord distance Ga between the outermost layer belt ply and the adjacent belt ply having a relationship such that 0.80≦Ga/φmax≦1.80 with respect to a maximum value φmax of outer diameters of the belt cords in the outermost layer belt ply and the adjacent belt ply.
