PNEUMATIC TIRE

A pneumatic tire 1 comprises: a tread portion 2 having a ground contacting surface 2s; a sidewall portions 3 having an outer surface 3s; a bead portions 4; a carcass 6 extending between the bead portions 4; and an inner rubber 10 extending between bead portions 4. The inner rubber 10 comprises a first portion 11 extending through the tread portion 2 with a first thickness t1, and a second portion 12 extending through the sidewall portion 3 with a second thickness t2 less than the first thickness t1. in a meridian cross section of the tire under the normal state, when a first reference point Pb1, a second reference point Pb2, a shoulder reference point Ps, a reference line segment Lb, and a shoulder line segment Ls are defined, then a length L1 of the shoulder line segment Ls is 85.9% to 89.3% of a length L2 of the reference line segment Lb.
