Estimating the term…
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 outer surface of the widest breaker ply when the tire is mounted in its design wheel rim and normally inflated has a curved shape in the tire axial direction and has a continuously decreasing radius from a point B to the adjacent edge of the breaker wherein point B is at a distance SP in the axial direction from the tire circumferential centerline equal to 20% of the distance from the tread center to the adjacent tread contact edge.
