Bryan, why did you need to replace the OEM wheels and tires on your F550? It came with 19.5 wheels and Continental tires, correct?
I haven't really had any issues with mine, and was pleasantly surprised how they performed this past winter.

The topic of overloading the rear axle, or front for that matter, comes up often and I read how many are comfortable in driving their trucks being ½ to 1 ton over their GVWR. They often state that they believe there is a cushion for this in the design. Well, I can only go by what I have learned and what I have seen. My rear axle was within 400 lbs, of being over it’s GVWR, or 100 lbs per tire. The problem was that the sidewalls were bulging and they had the maximum P.S.I. in them . It wasn’t unusual for someone to come up to me and let me know I had a low tire on the back. I always thanked them for their concern, but that was just the way the 225s always looked. The tires bulged so much, it made me nervous driving the back roads, with the rocks sticking up just reaching up to slice the bulging sidewalls of my truck. I knew early I needed to do something. The problem was, the rims were not wide enough to safely accept the next size up of tires. So the die was cast, I needed new wheels and tires.
The sidewall bulging on my OEM tires

The height and width difference between the OEM tire and wheel to the Rickson tire and wheel ~ 225 to 245
