I have 37x12.5r17 D rated Ridge Grapplers on my 2020 F250, and have zero issues handling empty or towing my 4500# trailer at interstate speeds. Empty, I run 40F/35R, towing, around 40F/45R.
I would not consider the tires to be a part of the problem unless there’s issues with the wheels, balance, alignment, etc. I’ve had Toyo MT’s, and two sets of RT’s, on previous vehicles, and I think I’ll have a hard time pulling away from these Ridge Grapplers unless I for some reason feel I absolutely need an load range E tire.
