I've been kinda fond of the 8.25's-thats what I put on my ol' 51 Ford F-5,and they fit fine. They're right-that's about as big as you can go. Another thing you want to watch is how close to each other they get. You see a lot of the one tons running too big tires on the back,and the sidewalls chafe against each other,building heat,especially if you load it down. Not as much of a problem on the bigger trucks,but if you want to try 9.00 or 10.00 tires,you'll want to keep this in mind.
