15x4 & 15x7 stock steelies?

Haven't tried but a 185/75/15 or a 165/80/15 should fit the rim.

Got some 185/65r15 on some draglites, but they are 3.5"(bought em years ago super cheap)
Just dont like how they sit on the bead.

Went back to the yard today and did what trunk searching I could.Most of the cars trunks were shut and no keys around to open em.They all had similiar rims like the one you showed Darter6.The centers were really pushed forward on them.If I had the time and equipment I would just buy 2 and swap the centers out to my desire,but thats not viable atm.

Did find the 5th ave there had 15x7's under them psuedo wire caps(thanks 73AbodEE).I stashed em so I can go back this weekend and bust the tires off,as to just buy the rims..... $30(with rubber) vs $10(w/o rubber) per copy.
