I seldom drive over 70mph, maybe a little over when passing. With the 4.30 ratio I usually drive about 65 mph so the speed limit on the 19.5's has not been an issue with me. There's not many 19.5 tires available but I don't think there's any more choice in the 17's. Maybe Ford is making other changes in the truck to keep the capacity up but I really think it's a mistake to make the 450 look like a 350.
