NITTO and others have XL rated tires if you are worried about load ratings. I run 255 45 17 on the front and 255 50 17 on rear of my 69 Bee and it drives great . Rims are 17x9 all around.
How is that relevant to the OP's question?
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.
