Show KELLY SPRINGFIELD "CATERPILLAR" TRUCK TIRES I . "Win H truck tire runs up phenom enal mileage it does not necessarily follow that all other tires of the same make can duplicate the performance," says the manager of the Ogden Electric Elec-tric Supply compan. distributors of the Kelly Springfield Caterpillar tires. J ' But when hundreds of a certain make of tire yield consistently remark-able remark-able mileage It is safe to assume that j their performance is more than merely mere-ly accidental. Kelly-Springfield Caterpillar tires are running up unusual mileage on ! , , hundreds of the heaviest trucks in ! i America. ta superiority lies partl in iis construction, but principally in its design. Jts system of side ;4 ir pockets j breaks up the destructive traction , wave ki-eps the tin: cool, permits ex- M V pansion under load compression and affords traction impossible with the or- ' dinary smooth tread tire. "It lessens the strain fn the engine, and because of the practical climina-! it ion of the traction wave its mileage! begins at about the point where the! service of the ordinary truck tire J ends." |
