Abstract
A pneumatic tire for a vehicle comprises a carcass ply extending between two bead regions and passing through a tread region which extends between two tread contact edges, a tread region reinforcing breaker radially outwards of the carcass in the tread region and a ground contacting tread surface curved in the axial direction wherein the curvature of the outer tread surface when the tire is mounted on its design wheel rim and normally inflated has a continuously decreasing radius from a point P which is at a distance SP in the axial direction from the tire circumferential center line equal to 20% of the distance from the tread center to the adjacent tread contact edge.
