Pneumatic tire

A pneumatic radial tire comprising:

• a tread having an outer surface which forms a tread surface;
• a pair of sidewalls extending from ends of the tread, respectively, substantially inward in a radial direction;
• a pair of beads located substantially inward of the sidewalls, respectively, in the radial direction;
• a carcass extending on and between one of the beads and the other of the beads and along and inward of the tread and the sidewalls;
• a belt laminated on the carcass at an inner side, in the radial direction, of the tread;
• and
• a liner located inward of the carcass, wherein
• outer ends of the sidewalls are located inward of ends of the belt in an axial direction,
• the liner includes a first inner liner extending on and between one of the beads and the other of the beads and along and inward of the carcass;
• and a pair of second inner liners extending from the ends of the belt, respectively, along the first inner liner substantially inward in the radial direction,
• the second inner liners are located between the first inner liner and the carcass,
• outer ends of the second inner liners are located inward of the ends of the belt in the axial direction,
• the first inner liner is formed by a first sheet, formed from a first rubber composition, being crosslinked,
• each second inner liner is formed by a second sheet, formed from a second rubber composition, being crosslinked,
• each second sheet has a reference end corresponding to the outer end of the second inner liner,
• in forming the liner, each second sheet is attached to the first sheet such that the reference end of the second sheet abuts against an outer surface of the first sheet,
• each second sheet has an inclined surface extending from the reference end so as to be inclined relative to the outer surface of the first sheet,
• an inclination angle of the inclined surface of each second sheet is equal to or greater than 10° but equal to or less than 45°,
• a base rubber of the first rubber composition includes a butyl rubber, and
• a base rubber of the second rubber composition includes a diene rubber.
