摘要： It is an object of the present invention to obtain a pneumatic tire in which separation of a tread rubber and a side rubber from each other at an interface therebetween can be substantially prevented and separation of the side rubber and a side wall rubber from each other at an interface therebetween can also be substantially prevented, and a production method of the pneumatic tire. The pneumatic tire is structured such that the interface between the side rubber 28 and the side wall rubber 32 appears, not at a side surface side of the tire, but at a ground-contacting side (i.e., low distortion portion) thereof. As a result, bending deformation acting at the interface between the side rubber 28 and the side wall rubber 32 can be reduced, and thereby separation of the side rubber 28 and the side wall rubber 32 from each other (i.e., cracks) at the interface can be prevented. Further, since the side rubber 28 and the side wall rubber 32 have the same or similar physical properties or composition, a possibility that the side rubber 28 and the side wall rubber 32 are separated from each other (i.e., a possibility of crack generation) at the interface therebetween can be significantly lowered.

摘要： A method of manufacturing a pneumatic tire having a bead guard of excellent spew-less appearance free from pair, comprising the steps of positioning the tire formed surface side edges (13-1SE, 13-2iSE) of the divided surfaces (13-1S, 13-2iS) of side ring pieces (13-1, 13-2), positioned adjacent to each other, of a side ring (13) formed by divideding annularly in inner and outer radial directions with respect to the center axis of a split mold (11) at a position corresponding to a recessed portion (15) forming a bead guard (5) in order to vulcanizingly form a pneumatic tire (1) having the bead guard (5) of trapezoidal shape in cross section by using the split mold (11) having a pair of annular side rings (13) and a multiple-divided tread part forming segment (12) engageably formed integrally with the pair of annular side rings.

摘要： A high-speed running pneumatic radial tire comprises a cylindrical crown portion, a pair of sidewall portions extending inward therefrom, a radial carcaas (7) extending from one of the sidewall portions through the crown portion to the other sidewall portion, and a belt (8) and a tread (9) successively superimposed on the crown portion outward in the radial direction of the tire. The tread has a plurality of rows of blocks (3) defined by a plurality of circumferential grooves (1a,1b) and by lateral grooves (2a,2b), and the belt (8) is comprised of at least two main cross-cord belt layers (8a) and an auxiliary belt layer (8b) arranged thereon. The auxiliary belt layer is formed by spirally winding a rubberized ribbon ply of heat-shrinkable cords (12) on the main belt layers (8a), in which an overlapped amount of the ribbon ply is made larger in a zone (B,C) of the tread substantially corresponding to a block row (3) than in a zone (A) of the tread substantially corresponding to a circumferential groove (1a,1b).
