I am wanting to know if a 15x10 rim can be run on a fox body with a 275/60/15 or 275/50/15 and fit in the stock wheel area. The class I want to run requires DOT tires and largest/widest tire that can be run is the 275 on a 15inch rim. If it can what it the offset/back spacing required to fit them on a fox body. I have and 83 GLX.
