By increasing the offset between the center line of the AA-1015-C disc wheel and the mounting flange, 1⁄4″ additional side wall clearance has been provided between dual wheel tires. This provides ample clearance even when balloon tires are used.
With the old wheels, the distance between the tires, measured from the center line, was between 7 1⁄4” and 71⁄2″, with the new wheels the distance measures between 7 1⁄2” and 7 3⁄4″. (See Fig. 1080.)
