ABSTRACT:
Disclosed herein is a pneumatic tire comprising a carcass composed of at least one cord ply extending between a pair of bead portions, an inner liner adhered to the inner surface of the carcass, and a rubber reinforcing layer made of a rubber composition different from and having a Shore A hardness higher than that of the inner liner and disposed at a lower part of the bead portion including a bead toe portion and a bead heel portion to form an outermost bead rubber at least at that region of the bead portion which comes into contact with a rim. In the tire, the rubber reinforcing layer is divided into an axially inside portion inclusive of the bead toe portion and an axially outside portion at a boundary surface located in an area between the bead toe portion and a position corresponding to 1/2 of a height of a rim flange, and the axially outside portion is extended over the height of the rim flange outwardly in the radial direction of the tire, and rubber of the axially inside portion is small in the Shore A hardness and abrasion resistance index and high in the breaking energy after heat deterioration as compared with that of the axially outside portion.
