ABSTRACT:
A pneumatic tire comprises a carcass extending around the tire from bead to bead, sidewalls and a rubber tread region which has a profile when considered in transverse cross section of a new tire terminating the sides of the tread in inner and outer shoulder regions respectively, each of said shoulder regions having a shoulder drop, which is defined by the distance in the radially inward direction from the point of maximum tire diameter to a shoulder point at the edge of the shoulder region, wherein when the tire is mounted on a scheduled wheelrim and inflated to a scheduled pressure, the tread region has its point of maximum tire diameter offset in the axial direction of the tire from the center line of the tire section in the direction of the inner shoulder, and the shoulder drop of the outer shoulder is greater than the shoulder drop of the inner shoulder such that the tread region has an asymmetrical profile.
