Original Abstract Submitted
A pneumatic tire comprises: a tread portion having a ground contacting surface; a sidewall portions having an outer surface; a bead portions; a carcass extending between the bead portions; and an inner rubber extending between bead portions. The inner rubber comprises a first portion extending through the tread portion with a first thickness t, and a second portion extending through the sidewall portion with a second thickness t. The first thickness t is more than the second thickness t. In a meridian cross section of the tire under its normal state, when a first reference point (Pb), a second reference point (Pb), a shoulder reference point (Ps), a reference line segment (Lb), and a shoulder line segment (Ls) are defined, then a length (L) of the shoulder line segment (Ls) is 85.9% to 89.3% of a length (L) of the reference line segment (Lb).
