A racing tire for oval race courses, wherein a profile of an outer region of a tread portion which is positioned to be further axially outward toward an outer side of a race course than a center line of the tire and a profile of an inner region of the tread portion which is positioned to be further axially inward toward an inner side of the race course than the same center line are asymmetrical, an outer diameter and thickness of the outer region of the tread portion being larger than an outer diameter and thickness of the inner region of the tread portion, a difference between the outer diameters of portions of the tire spaced from the center line of the tire in the opposite widthwise directions from the center line by a distance corresponding to 45% of a maximum width of the tire being set to 0.5-5.0% of the outer diameter of a portion of the tire on the center line.
