<p>PROBLEM TO BE SOLVED: To obtain a pneumatic tire capable of effectively reinforcing a carcass cord while suppressing increase in a tire weight.SOLUTION: When a distance between a first vertical line VL1 passing the center of a bead core 18 and a second vertical line VL2 passing a tire maximum width end P, measured in a state of folding up intervals between a bead part 12, a tire side part 14 and a tread part 16 between a rim flange 42 and a step part 40 by loading a weight in a state of mounting on a rim 38 is defined as L, a radial direction outer reinforcement layer 34 and a radial direction inner reinforcement layer 36 of a dimension of 0.58-0.62 L are arranged from the first vertical line VL1 to the second vertical line VL2, along a carcass ply 20 so as to reinforce a carcass cord.</p> |
