Abstract
To improve traveling stability, riding comfort, high-speed durability, etc., the uniformity in the main belt of a belted tire is improved by dividing an auxiliary layer into at least three areas in an axial direction of the tire, and both ends of the three divided auxiliary layers are bonded in the divided areas at different bonding positions, respectively, in circumferentially spaced relationship to each other. In particular, lateral force variation of the tire is reduced and separation trouble at the auxiliary layer bonding area can be settled.
