For reference, the 15x9's with 4 3/8" of backspace that autoxcuda runs with his 245/50/15's stick out a full 1" outside of where my 275/35/18's are. I'd have to fully flare my fenders to pull that off. Now, those 245/50/15's are only 24.7" tall, compared to the 275's on my car at 25.6", which is a big part of it. The other part is those fenders have been pushed out pretty significantly, that's not something you can run without doing some bodywork, even on a Barracuda.
