The steel code for rubber additional strength and the radial tire which uses that

摘要

(57) Abstract Constitution With steel code of 1+6+12+1, coreAt the same time straight, the 1st and 2nd sheath with the same direction it differsTo be twirled with pitch, as for the spiral in the same direction as the sheathTwirling, as for die attaching factor of 1st and 2nd sheath each 70 - 90% 1st sheath and as for 2nd sheath at abbreviation same wire diameter, core and seaAs for ratio of wire diameter of su with 1 - 1.25, ko which excludes the spiralThe rubber to which tensile strenght of do satisfies 300 - 400kgf/mm2The steel code for additional strength the radial tire which uses that. Advantages Code break characteristic after the rough road run, rough road run - it is lowBoth code break factor after the internal pressure run until recently and the known steelTo be improved more substantially than the code, endurance of the steel codeYou improved, could extend life.
