If you want the 19.5's, just go to ebay, and get a set from all the people that decided they didn't like them.

The 19.5's are hard to balance right, and the speed rating I believe is 65mph. The tires also go for around $275-600 per tire and you just don't pull onto Joe's garage in the middle of nowhere and get a replacement if you shred one. You would also be smart to have a matching spare, but that wouldn't be to critical if you kept the tire height close to the ones you took off.

Unless you really want a different look or need to spend money, just get another set of the Michelin's. The truck will ride like it did new. Mine came with Firestones and when they go, I'll go up to Michelin tires unless I get a killer deal on some take-offs.

19.5s can be no harder to balance than others--have seen some Michelins that needed to be replaced because of balance problems. As to replacements--yep, little harder to find at Joe's Garage, but that is why truck stops are in business. And if you ruin one, you probably had to work much harder at doing that than with regular tires. 203k miles, one screw thru sidewall...
Also, have been monitoring eBay looking for a set--can't find those takeoffs that others don't like.
Speed rating is 85 on the OEM Continentals on my 450, you might be confusing them with some 17.5 trailer tires.

I went with 18 inch tires for the 7500 lbs capacity. My axle has over that in capacity though Ford shows 6200,. Air the front to 70 and the rear at 72. With 5 spring plies on each side and 1 overload/helper ply the F250 rides better then my stock 2500 GM loaded or empty.
I have never changed air pressures loaded or unloaded and rotate the tires at 8000 miles.
The last 2 sets or tires have been bought used at $400 per set of 4. Usual from owners that did not like the ride of these heavy tires.
Forget the helper/overload for capacity, by the time they are loaded the truck will drive rough due to loading the top of axle plate. I added plies till the plate does not touch the spring plies. You cannot load the truck till the spring rest on this plate. The plate is meant for rear axle anti roll when braking and accelerating. But lots do load this plate. That's why the Ford load capacity is shown.

Yes you will find the at truck shops and city's along the interstate but not on hwy 50 in Nevada or similar highways. Blowouts from debris would not be a case of working them. It happens all the time. When I went to the websites of some of the tire manufactures for truck tires the specs said 65 mph. I thought that was odd. I also seen quite a few 19.5's wheels for sale on ebay a couple of months ago.

I decided they weren't for me, and others have come to the same decision . On the other hand some like them.
