Will 15X9 fit a 65 barracuda in the rear?
A 15X9 will not fit a stock Barracuda.
Well it might if use a tire with no buldge kind of like the low riders do. That in my opinion kind of defetes the purpose.
I have found a 15X7 The best size to get max tire under the 65 Barracuda. Although 15X8 would work fine too I think.
You will also have a little rubbing in hard corners and driveways with a 245 tire even with perfect backspace
