Abstract:
This pneumatic tire (1) is provided with: 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) comprising steel belt cords covered with coating rubber, the belt layer being disposed on the outside in a tire radial direction of the carcass layer (13). An inter-cord distance (Ga) between the outer-most layer belt ply (fourth belt (144)) and an adjacent belt ply (third belt (143)) has the relationship 0.80 ≤ Ga/ϕmax ≤ 1.80 with respect to a maximum value (ϕmax) of outer diameters (ϕ4, ϕ3) of the belt cords (1441, 1431) in the outer-most layer belt ply (144) and the adjacent belt ply (143).
