OK so I was wondering what size wheel and backspacing would I need to put a 29x12.50 micket thompson sportsman street tire on a stock width 8-3/4 in a 68 dart? Anybody running a combo like that? I was guessing a 10" wide rim with a 7" backspacing? I have measured from the frame out to the lip on the qtr and its 0ver 15" wide so should be plenty of room with the right wheel and tire combo. Thanks in advance for any input.




7.5" is what I needed with that tire and a stock width a-body 8-3/4 housing and a 15x10 wheel (not many choices there either)...needless to say I got rid of those tires in a hurry when all they did was spin no matter where I used them






Same here !5x10 7.5 backspace using 295 50 15 eagle but had a lot more room inside
