摘要：A pneumatic tyre (1) comprising a carcass (6) extending around the tyre (1) from bead (7) to bead (7), sidewalls (4) and a rubber tread region (2) which has a profile when considered in transverse cross section of a new tyre terminating the sides of the tread in inner and outer shoulder regions (5) respectively, each said shoulder region (5) having a shoulder drop (a,b), which is the distance in the radially inward direction from the point of maximum tyre diameter (M) to a shoulder point (P) at the edge of the shoulder region (5), characterised in that when the tyre (1) is mounted on a scheduled wheelrim and inflated to a scheduled pressure, the tread region (2) is asymmetric having its said point of maximum tyre diameter (M) offset in the axial direction of the tyre from the centre line (CL) of the tyre section in the direction of the inner shoulder (5i), and the shoulder drop (a) of the outer shoulder (5o) is greater than the shoulder drop (b) of the inner shoulder (5i) such that the tread region (2) has an asymmetrical profile. <IMAGE>
