PNEUMATIC TIRE

摘要

[Subject Matter] To provide a pneumatic tire 22 having excellent durability and steering stability. [Solution(s)] In the tire 22, a fitting portion 66 to be fitted to a rim has a bottom surface 72 positioned on its radially inner side and a side surface 74 positioned on its axially outer side. The bottom surface 72 includes a heel 92. The side surface 74 includes a concave 94. When the axial outer edge (P1) of the bottom surface 72 is set as a first base point, when a virtual straight line that passes through the first base point (P1) and extends in an axial direction is set as a first base line (X1), and when a virtual straight line that passes through the first base point (P1) and extends in a radial direction is set as a second base line (X2), the heel 92 is shaped as a first arc having its center on the first base line (X1) and originating at the first base point (P1). The heel 92 makes contact with the side surface 74 at the first base point (P1). The concave 98 is recessed from the second base line (X2) in an axially inward direction. The axial distance (d) from the first base point (P1) to the bottom (Pb) of the concave 98 is at least 1.0 mm but no greater than 2.0 mm.
