Show u WHY CORD TIRES GIVE BETTER MILEAGE Thoro nro two woll-known classes of tiros tho squaro-wovon fabric and tho cord tiro. In tho square-woven fabric ' tiro tho threads In each ply run In both directions, alternating over and under as In a plcco of ordinary cloth, i In tho cord tiro, tho threads or cords : In each ply run parallol. Slnco square-woven fabric cannot bo thoroughly impregnated with rubber at the points whore tho threads cross, i lloxlng at thces points will cbubo a .iiMUmMj m, I m sawing action and tho generating of Internal hoat. It hns been demon Btratcd very clear by experiment, ac- cording to tha United Statps Tiro Company, that when tho tompcrnturo resulting from intomal heat renchea m 230 degrees, Vulcanized rubber cruin- J bios Into minute particles. This ultt- matoly causos a blow-out, A heat of S1G5 dogrcos Is not an uncommon tern H poraturo In a tiro when driven at a fj high speed; thin Is particularly truo J of largo truck tlroa. H In tho caso of cord tlrea, each H thread Is ombodded In tho rubbor compound and tho lntornal friction Is H rcducod to n minimum. A brief sum- mary of tho advantages doiivod from tho uso of cord tires would lncludo H easier riding, duo to greater realloncy; H saving of gasoline nnd oil; saving of H machlnory, nnd more miles per dollar. |
