Fattest Tire under a 73 Dart swinger

If it helps at all I have 235 60 14 BFG radial TA's under my 70 Dart on stock 5.5 wide ralleye rims and have at least 1 inch or more clearance on both the unmolested lip and the leaf springs. 255's would have probably fit but may have scrubbed on hard cornering or bumps. I went to my local tire guy who said that it was no problem to order and mount a set for me to try and if they hadn't worked he would have sent them back and ordered the next larger size. I don't care what the government says about the economy,it's still hard, and I'm sure your local mom and pop tire guy would be willing to work with you as he is probably hungry for business.
