I am in the planning stage of tires and rims, what is the widest tire and rim combo that will fit under the car without rubbing?
I am thinking about either 15" or 16" rims, what rims width and offset at I looking at ???
Any good suggstions and pictures of how they look on your car :D :D
Thanks Gary

Hey Gary, Paul Ford has some pretty big (16?) tires under his 66. I also have some 275/60 15 you could try on yours for an idea of what will work.
