comparing backspacing...

[Paulywalnuts446]

ok hows the fit on a fox mustang with a 15x10 inch rim with a 5.5 bs compared to a 6.5? do both of them fit? do u guys have any pics? b/c i have the oppertunity to get rims but they are 5.5 BS and i thought you needed a 6.5 to fit?

10's w/ a 5.5 b/s will stick out and most likely rub the outer fender well like crazy.

The 6.5's will most likely rub the inside as well as the quads. You will also need a wide tire to fit that rim which will add to the problem. A spacer may help but then throws the w/t combo outside even more.
