I am going to use 15" Centerline Auto Drag wheels and I would like to know whats the largest(widest) rear tire I can run on 68 Cougar with what size rim and backspacing should I use , hoping maybe either 255/60-15 or 275/60-15 tires will work
I have P235R60/15's up front and 275's in the rear with 1" extra lift from air shocks. This was the set up on the car when I bought it. I only get rub on the drivers side rear when I turn right up a slight curb or driveway. I upgraded to Goodrich Radial T/A's from Pep Boy specials. I think if I went with 265's instead that might have been just enough to eliminate that.
