摘要： A pneumatic tire can include a plurality of recesses arranged in a tire circumferential direction. Each recess can include a sidewall surface extending inward in a tire axial direction from an outer surface of a bead portion, and a bottom surface defining a depth of the recess. In a cross-section of the recess including a tire rotation axis, a sidewall surface located on an outer side in a tire radial direction and the bottom surface can be smoothly connected via an arc portion. The arc portion can have a radius of curvature equal to or larger than the depth of the recess.

摘要： A rim guard of a tire has a top, an inner surface, and an outer surface. A contour of the inner surface is represented by a circular arc, and the circular arc has a radius of not less than 20 mm and not greater than 30 mm. A contour of the outer surface is represented by a circular arc, and the circular arc has a radius of not less than 100 mm and not greater than 500 mm. In a radial direction, a position of an outer edge of the outer surface coincides with a cross-sectional width specified position, or the outer edge of the outer surface is located outward of the cross-sectional width specified position.
