Abstract

PURPOSE: To protect the said tire from separation by a method wherein a reinforcing rubber stock with a special hardness equal to or more than a specified hardness of a bead filler is made up of tonguelike stock in which the thickness begins to grow from the bead core and takes the maximum value at the end of the bead filler.
CONSTITUTION: The said tire is composed of a bead filler B and a reinforcing stock C. The former B is wrapped in the 1st carcass ply 1, a bead core 2 and the folding part 1a of the 1st carcass ply 1 and has a Shore A hardness of 90 or more. The latter C is composed of a togquelike stock which is located on the outside of the 1st carcass ply 1 and the folding part 1a and is wrapped in the 2nd carcass ply 3, has a Shore A hardness of 80 or more, begins to grow in thickness from the bead core and takes the maximum thickness at the end of the bead filler. The bead filler B is wrapped completely in the reinforcing rubber stock C and the folding part 1a is prevented from separation due to bending fatigue at the folding part 1a.
