Abstract (en)

[origin: WO9958349A1] The loss of tire contact patch area along the tire's inside shoulder, relative to an oval race course, which occurs during chassis roll and lateral deflection, is reduced by providing an asymmetrical molded tire. The tires are defined by an asymmetrical outer tread profile and the tires are mounted on the rear axle of the race vehicle such that the axially outer portion of the asymmetrical tread region of each tire, relative to the race course, has a greater shoulder drop, wherein the shoulder drop is the difference between the maximum radial diameter of the tread measured on the outer tread contour and the diameter of the tread at the tread edge, than the opposing tire shoulder.
