Abstract
PURPOSE:To prevent the generation of separation by setting the adhesive quantity of an adhesive agent in specific proportion and as well using a carcass cord which is subjected to impregnation treatment in such a way that penetrance at intervals of a fiber filament satisfies a specific relational expression. CONSTITUTION:A tire is fixed in a pair of beads and has a carcass layer of at least one layer extending in the tire radius direction in parallel. In this case, as a carcass cord forming the carcass, an adhesive treatment agent with a rubber compound is subjected to adhesive treatment of 8-25% in solid portion and as well is used a cord which is subjected to impregnation treatment from a strand surface at intervals of a fiber filament with proportion satisfying next equations. Namely, when a strand radius is ro and the impregnation depth of the adhesive treatment agent from the strand surface is r, it is set that r/ro>0.4. With this arrangement, adhesive force in cords is enhanced, and thereby separation and turned up separation are restrained.
