With that much backspacing you might have problems with the tire rubbing on the frame. With lower backspacing the tire sticks out more, with more backspacing the tire will be closer to the frame. I have 3-5/8" backspacing and it just about prefect. That means those tires will be like over 2" closer to the frame then mine, they probably won't work, but I have 15x10's so its different. And I'm running 13.5" wide tires, and there pretty wide, hope that helps any. <img src="/forums/images/graemlins/cheers.gif" alt="" />
