Sorry, I am not too knowledgeable about tires and wheels that will fit on the second gens, but I just wanted to ask if you had any traction boosting devices? I run South Side Machine Lift Bars and they really give some added traction. I have heard good things about Cal Tracks Bars too. As far as the first Gen, I run 8'' rims in back with 255 rubber and they fit fine. Good luck to you in the war against the 'stangs.
