With 15" wheels,... it's all about the backspacing.
You can run a 15x7, 15x8, 15x10 and not rub a stock lower control arm,... as long as the wheel has approximately 3.5" of backspacing.
And with that said,... now you need to look at what's going to rub the fender lip.
Bigger diameter wheels can run more backspacing.
