I have 3 Goodyear Polyglas GT G60-15 These are originals that would make excellent trunk spares for any 70-72 GS or GSX that came with the factory 15x7 wheel option. or If you can find one more,you'll have a set. All 3 have pretty decent tread, with one showing just a little more wear on the inside outer edge(was probably a front tire) Asking $225 for the 3 of them.
