| 20150352908 | PNEUMATIC TIRE - Provided is a pneumatic tire including a carcass constituted of at least one ply including a ply main body and ply turn-up portions, and a recessed portion formed to be recessed inward in the tire axial direction at an outer surface of the tire in a region between a rim separating point and the tire maximum width position in each sidewall portion. In a section taken along the tire axial direction in a non-rim assembled state, an angle α is defined as an angle that an outer surface straight line defined by each bead back face portion passing the first intersection and the second intersection forms with respect to the tire axial direction, and the angle α is in the range from 70 to 100°. | 12-10-2015 |
