Abstract: When a tire that is mounted on a specified rim, inflated to an internal pressure of 50 kPa, and placed in a no-load state is viewed as a cross-section from the tire meridian direction, a position of 1.30×Hf on an outer surface of a sidewall portion, taking a rim flange height (Hf) of the specified rim as a reference, is defined as a point (P), a foot of a normal line (L) drawn from the point (P) to a carcass line of a main body portion (131) of a carcass layer (13) is defined as a point (M), and a point of intersection of the normal line (L) and a carcass line of a folded back portion (132) of the carcass layer (13) is defined as a point (T). At this time, a distance (a) mm from the point (M) to the point (T), a distance (b) mm from the point (T) to the point (P), and a specified load (x) kN have relationships such that a=0.019×x+13.3 and b=0.052×x+21.6, with a tolerance of not less than 0% and not more than 20%.

Abstract: 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).
