    Abstract: A pneumatic tire which includes a carcass having a carcass main extending from a bead core in one of the bead portions to a bead core in the other bead portion, and a pair of carcass turnups extending axially outside the carcass main; a tread rubber disposed in the tread portion; a sidewall rubber disposed in each of the sidewall portions; and a wing rubber interposed between the tread rubber and sidewall rubber. Each of the carcass turnups extends from axially outside of the bead core to a point in the sidewall portion. While extending from axially outside of the bead core to the point in the sidewall portion, the carcass turnup approaches the carcass main and adjoins the carcass main from a first radial height to a second radial height and then separates from the carcass main from said second radial height so as to form a separating part. The wing rubber has a JIS type-A durometer hardness of from 45 to 60 degrees, and a radially inner part of the wing rubber is inserted between said separating part and the carcass main.
