Abstract

Disclosed is a rubber pneumatic tire for vehicles which has two beads for bearing against the rim of a wheel. Embedded in each bead is a core ring which has a shaped ring and around which a carcass insert which is embedded into the rubber material of the tire is laid, for anchoring same. Each shaped ring comprises a material which chemically bonds to the rubber material, and contains a winding of high-strength fibres, which is laid in the shaped ring and which holds together and strengthens the shaped ring.
