An improved radial tire is disclosed which contains a rubber filling over the bead core wherein the rubber filling consists of two structural shapes being adjacent to one another. One shape is formed from a low hardness compound while the other is made from a high hardness compound with the latter shape being directed towards the axially outer zone of the bead. A sheet of a hard compound is placed in the axially outermost position of the bead adjacent to a strip of metal cord fabric which in turn is placed next to the high hardness structural shape. This structure prevents the metallic cord fabric from detaching itself from the tire which occurs when conventional radial tires are subjected to normal service conditions. It also prevents separation between the rubber filling and the carcass plies when the tires are subjected to severe service conditions. |
