Abstract
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.
Claims16
A pneumatic tire comprising:
- a tread;
- and
- a pair of side portions each located radially inward of an edge of the tread, each side portion including a main body and a rim guard projecting axially outward from an external surface of the main body, wherein
- the rim guard has a top, an inner surface located radially inward of the top, and an outer surface located radially outward of the top,
- a contour of the inner surface is represented by a circular arc having a center at an outer side of the tire, 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 having a center at the outer side of the tire, and the circular arc has a radius of not less than 100 mm and not greater than 500 mm, and
- 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.
