Abstract

A pneumatic tire includes a tread portion, a pair of sidewall portions, a pair of bead portions, a carcass extending between the pair of bead portions, and an inner rubber extending between the pair of bead portions on an inner side of the carcass. The inner rubber includes a first portion extending in the tread portion with a first thickness and a second portion extending in each of or one of the pair of sidewall portions with a second thickness. The first thickness is greater than the second thickness. In a tire meridian cross-section, a cross-sectional area of the inner rubber is in a range from 1.5% to 10% of an inner-cavity cross-sectional area of the pneumatic tire.
