9. A pneumatic radial tire according to claim 8, wherein the widthwise outer end of the lateral rubber layer is extended outward from the widthwise outer end of the widest-width belt ply in the widthwise direction.
10. A pneumatic radial tire according to claim 8, wherein a cushion rubber layer is interposed at least between the each widthwise outer end portion of the widest-width reinforcing ply and a portion of the belt ply overlapped therewith, and
wherein the lateral rubber layer is made of rubber having a JIS hardness higher than that of the cushion rubber layer.
11. A pneumatic radial tire according to claim 1, wherein the widest-width belt ply is arranged adjacent to the belt reinforcing layer.
12. A pneumatic radial tire according to claim 1, wherein at least one belt ply is arranged between the widest-width belt ply and the belt reinforcing layer.
13. A pneumatic radial tire comprising a carcass layer toroidally extending between a pair of bead portions, a belt layer arranged on a radially outer side of the carcass layer and comprised of at least two belt plies embedded with reinforcing elements inclining in opposite directions with respect to an equator of the tire, and a belt reinforcing layer arranged between the carcass layer and the belt layer and comprised of at least one reinforcing ply embedded with reinforcing elements extending substantially in a circumferential direction, provided that a width Wp of a widest-width reinforcing ply among the reinforcing plies is 0.6 times or more a tire width W, in which only a widest-width belt ply among the belt plies is arranged so as to locate each widthwise outer end thereof outward from each widthwise outer end of the widest-width reinforcing ply in the widthwise direction, and a cushion rubber layer is interposed at least between the each widthwise outer end portion of the widest-width reinforcing ply and a portion of the widest-width belt ply overlapped therewith, and the widthwise outer end of the cushion rubber layer is located inward from the each widthwise outer end of the widest-width belt ply in the widthwise direction, and when a total gauge of coating rubbers mutually opposed to each other in the mutually adjoining reinforcing ply and belt ply is T, a rubber gauge G including the total gauge T between the each widthwise outer end portion of the widest-width reinforcing ply and the portion of the belt ply overlapped therewith including the cushion rubber layer interposed therebetween is rendered into a range of 2-10 times the total gauge T,
wherein a lateral rubber layer made of rubber having a JIS hardness equal to or more than the JIS hardness of the coating rubber for the reinforcing ply(s) is arranged at each widthwise outside of the widest-width reinforcing ply.
