摘要： Provided is a pneumatic tire having the structure where a carcass ply is wound around bead cores from the outside in the tire width direction to the inside in the tire width direction, and both end portions of an inner liner extend between beads and the carcass ply. A lightweight and highly rigid tire can be acquired. The tire can also enhance steering stability performance thereof. The pneumatic tire includes: a pair of left and right beads including bead cores 3a; a carcass ply extending between the bead cores; and an inner liner 4 disposed on an inner peripheral side of the carcass ply 5, wherein the carcass ply 5 is wound around the bead cores 3a from the outside in the tire width direction to the inside in the tire width direction, and both end portions of the inner liner 4 extend between the beads and the carcass ply.
