Beschreibung
Zusammenfassung:	A tire includes a tread portion having at least one circumferential main groove extending in a circumferential direction of the tire and spaced axially apart from an equator of the tire. The groove has a circumferential profile shape including an inner wall portion extending radially inward from an axially inner edge of the groove, an inner arc portion continuous with the inner wall portion and having a smaller radius of curvature than the inner wall portion, an outer wall portion extending radially inward from an axially outer edge of the groove and having a larger length than the inner wall portion, an outer arc portion continuous with the outer wall portion and having a smaller radius of curvature than the outer wall portion, and a groove bottom portion extending straight from the outer arc portion toward the inner arc portion while being inclined in a radially inward direction whereby the groove bottom portion has a constant radius of curvature.
