67 Barracuda Rear Tires/wheels

Not to many choices in 14" tires any more. About the biggest you are going to find is a 245/60-14 and these will fit just fine providing the custom rims you got don't have a radical back spacing.

I am running 255/60-15's on 8" wide rims on the back of my 68 Barracuda. I have about 1/2" clearance between the side wall of the tire and the spring and about 1.5 " clearance to the outer wheel well. If the wheel had less back spacing I could fit a larger tire.
