Abstract

PURPOSE: To improve durability and ride comfortableness by a method wherein a side portion rubber layer and a bead filler are integrally formed to constitute a composite rubber belt, and the folded end portion of a carcass ply layer and the end portion of the belt are sandwiched between the bead filler and a chafer strip.
CONSTITUTION: A radial-ply tire comprises a tread 9 and at least one layer of carcass ply 3 extending from one bead portion to the other, each bead portion including a bead filler 6 located on a bead core 5. The tire also comprises a belt layer 8 located between the tread 9 and the carcass ply layer 3, a pair of chafer strips 2 located on the axially outer side of the bead core 5, and a pair of side portion rubber layers 7. The layer 7 and the bead filler 6 are integrally preformed to constitute a composite rubber belt. The folded end portion of the carcass ply layer 3 and the end portion of the layer 7 of the composite belt are sandwiched between the bead filler 6 and the chafer strip 2.
