I was very careful about that possibility and made the tire shop bring in a rim from their warehouse and put it on the truck, front and back to make sure I would have clearance. Went with the 225/65 to ensure that very little if any tire would extend past the rim edge. I am pretty sure that if I had chosen any wider a rim, I would have had to go with a negative offset rim on the front.
Picked up a '53 GMC rolling frame last weekend with what is supposed to be a 261 power plant.
As soon as I get out there and clean it up, I will be able to run the numbers on it so I will have more info on it later.
