Provided is a bias tire includes a carcass extending between a pair of bead portions, a pair of sidewall portions, a tread, and a reinforcement layer (), formed by cords (Cb), disposed so as to cover at least a portion of a tire circumferential edge (BEi) on the inner side, in the tire radial direction, of the innermost ply (Bi) of the carcass in a tire half portion (HFa) on a side where, as a cord (Cb) of a tire circumferential end on the inner side, in the tire radial direction, of the innermost ply (Bi) approaches the tire circumferential edge on the inner side, in the tire radial direction, of the innermost ply (Bi) along the tire circumferential direction, the cord (Cb) is inclined so as to separate from the tire equator (CL).

Bias tire and method for manufacturing same

A pattern generatorproduces a predetermined pattern signalwhich is an electric signal, and a LD output lightof light signal is produced by inputting the pattern signalto a plurality of semiconductor lasers (LD)as a pump light source. To make a output lightto be a pulsed light not following a surge pulse rectangular, a fiber laser modulatoris configured that the pattern signalgenerated by a pattern generatorincludes four phases power level: low powered phase, power rising phase, high power phase and power decreasing phase.
