MT 275/60/15 ET Radials

I had a set of the 275/60 MT's on my '67 Valiant. I had the Mopar Performance 3/4" offset spring relocation kit which allowed me to run this tire on an 8" Wheel Vintiques rally wheel with a 3 5/8" backspacing. The tire will just clear the leaf spring and be inside the wheel well with this set up. If your leaf springs are in the stock location, the tires will hit the leaf springs with the 3 5/8" backspacing, forcing you to use a wheel with about 3 1/4" backspacing max. I would definetely relocate my leaf springs with either Mopar spring relocation kit, the one mentioned above or the other kit which moves the springs inboard 3".
