what's the widest tire that can fit on 71 swinger

Sorry to repost guys. I thought it would help to change the title but couldn't figure out how to do it on the old thread.

Got some rallys, I need to add some tires, but need to know how wide I can go without rubbing. I know the back wheelwells will restrict me and I am not sure about the pivoting of the front wheels.

Would 225/70/14 be too wide?
