Abstract
A pneumatic tire comprises a tread portion, a pair of sidewall portions, a pair of bead portions, a bead core disposed in each bead portion, a carcass comprising a ply of carcass cords extending between the bead portions through the tread portion and sidewall portions and turned up around the bead core in each bead portion, and an inner liner made of air-impermeable rubber extending on the tire cavity side of the carcass from one of the bead portions to the other. The radially inner end of the inner liner is located radially inside the radially innermost end of the carcass. In a radial region between the radially innermost end of the carcass and the radially outermost end of the bead core, the thickness of the inner liner is not less than 0.15 time but not more than 4.0 times the cross section diameter of the carcass cord.
