Abstract: A tread configuration for a vehicle tire, including at least two adjacent circumferentially oriented rows of profiled blocks. The rows are separated from one another by respective circumferential grooves. The base of each groove extends parallel to the circumferential direction. A respective side wall on each side of the base extends radially outwardly from the base and forms side walls of profiled blocks of an adjacent one of the rows of blocks. Radially outer end portions of the side walls of the grooves are essentially oriented in the circumferential direction and have their contour divided by a plurality of axially oriented offsets.

Abstract: A lower sidewall construction for radial ply tires characterized by improved in-service stability and structural strength is disclosed. The tire includes first and second bead units, at least one radially extending carcass ply, the end portions of which are each turned up around one of the bead units, and a radially extending square-woven fabric reinforcing strip positioned between each of the bead units and the carcass ply. Each of the reinforcing strips extends throughout a major portion of the respective lower sidewall of the tire, the radially inward end of each of the reinforcing strips extending to the core of its corresponding bead unit and the radially outwardmost portion of each of the reinforcing strips being in direct contact with, and adhering to, the carcass ply.

Abstract: Reinforcement for a pneumatic tire for vehicles, comprising a first, inner belt ply, a pair of lateral strips connected to the free edges of the inner belt ply, the lateral strips and the inner belt ply lying in substantially the same plane, and a second, outer belt ply having a pair of opposed flanges which fold over and hem in the lateral strips and at least the marginal areas of the inner belt ply. The lateral strips are substantially spaced apart from the folded edges of the outer belt ply, so that the outer belt ply is superpositioned on itself in the areas between the folded edges of the outer belt ply and the free edges of the lateral strips.
