Moving to 19.5" rims/tires

I'd really like to up the weight capacity on the rear end with a move to 19.5" rims and tires. I know this doesn't change the sticker, but it does give me a bit more piece of mind. I know Rickson makes some ugly steel wheels, and Vision makes some aluminum's...Any experiences with making the move to 19.5?
Thanks

Are you aware the 19.5 inch tires don't have as high a speed rating as the stock wheels/tires? Just saying, for safety concerns if high speed interstate driving is important to you.

The speed on the Ford F450 is restricted to a maximum of 85 mph because of the 19.5 inch wheel/tires that are standard on that truck.

I've run american force 19.5" s for 8 years with no issues at high interstate speeds. Our pickups haul livestock all over the Midwest. We run Goodyear G622 traction all the way around, getting 100,000 miles on them pulling loads every mile. American force uses my pickups in their 19.5" advertising. I've since gotten rid of our 1 tons to reduce my gcwr due to the enforcement of the DOT laws I have to abide by, 2500 put me under 26,000 lbs. Combined.

I did not know that! I don't drive this thing faster than 85 anyhow, but that's good to know.

If you do go to em be prepared to be scared to death for the first few thousand miles. You'll get some pretty good tread squirm with them until you get some miles on them. Also most tire shops like les schwab will charge you to rotate even of you buy them from em cause they are no longer passenger vehicle tires so you don't get the perks like free rotation and free flat repair in x amount of miles. You will get quite a few miles out of them though of you keep em rotated and proper pressure.

I ran Rickson steelies with Bridgestone M729's on my '06 3500 SRW for a while.

Make sure all your dental fillings are tight........

They do increase both your weight capacity and effective axle ratio but ride like a buckboard. Per Bridgestone, you must inflate to at least 80 PSI due to the sidewall and bead design, 110 PSI for max load (5500 lbs). I see you are pulling a pretty big 5'er and you have 3.42 gears. You will want to see what your effective axle ratio will be with the 19.5 rubber, I'm guessing about about 10% lower (numerically) which will be around 3.08......not the best for towing heavy.
