<p>A pneumatic tire having improved speed, stability and cornering characteristics is disclosed. The tire is formed with an annular, axially extending protuberance or bulge formed in the shoulder region on each side of the tire and also has, between the carcass and tread thereof, a reinforcing breaker or belt whose width is wider than that of the rolling contact surface of the tread with the ground and whose lateral sides correspondingly extend into the axially extending protuberances. The radially external surface of the tread and the axially outward protuberance, as viewed when the tire is mounted on a vehicle, are connected along an uninterrupted, convex profile. The width of the reinforcing breaker imparts improved high speed capability and stability to the tire; the uninterrupted profile connection between the radially external surface of the tread and the axially outward protuberance imparts improved cornering performance to the tire; and the axially projecting protuberances provide improved hazard resistance against cuts and penetration of the tire sidewalls.</p> |
