Im guessing this bike is all original and seemingly never or barely ridden.
Probably common for that time; our '69 Sears Spyder (single-speed cousin to this muscle bike) was spec'ed with 24 x 1 3/4 rear, 24 x 1 3/8 front, albeit both with "street" tread. The rims are even different widths, to accomodate.
