73 dodge dart swinger wheel and tire size?

I am running 275/60/15 tires on the back of my 73 dart. The odd thing is, when i tried to run them with the 7 1/4 they hit the springs so bad you couldn't bolt them on even. when i went to an A body 8 3/4 they fit fine. same exact tire and rim i had tried previously with the 7 1/4. maybe i had some funky rear that was narrower than normal or something... I really don't know. just keep that in mind here.

that being said, with my A body 8 3/4 I can fit 275/60/15 tires on police wheels. It is tight, it might not work on some cars without massaging the fenders a bit. if you want to play it safe get something a few sizes smaller. The police wheels have the best possible backspacing for these cars.

I run 245/60/15s up front so the back tires don't look as big as they are.
