Max PSI on my tires is 65 cold. Never like towing/hauling at the max. I prefer having about 5psi less than what is recommended cold.
The whole 250 vs. 350 debate. Same engine. Same breaks. I take my time and give myself lots of space. Wasn't looking to get into that debate here. I don't have any towing issues. Just a steering problem.
I appreciate all the advice.

Since you did not specifically reply to me... I will indulge myself....
There is no such thing as "bum steering"....
It's Bump Steer....
This is a side effect of a difference in geometry between the following:
Steering box to steering knuckle (tie rod)
AND
Opposite frame and axle (drag link)
Due to incorrect geometry, the steering angle changes for a specified amount if steering input as the suspension cycles.
You would notice this when hitting bumps or as the road changes enough to cause a suspension cycle.
Wear would not enhance this side effect as it is not related to wear... Only and specifically the differences in geometry.
However If the tie rod and drag link have excessive wear, they could cause the wandering you describe as well...
But so could poor alignment without enough caster. This is very common.

I noticed my front end has a little squirm to it when I first had my M/S tires installed. It slowly getting better. I run with 55/65 psi on my truck. Then I inflate accordingly when I tow my rig.

I don't understand .... that is the published hitch weight for your trailer from the factory????? Add 60lbs of propane, whatever you carry in the bedroom and the weight of your hitch and you are well over 3500 lbs.. It may tow it fine but you are killing your truck by overloading it. Good luck and travel safely, Hank

Anyhow,
Even w/my prior TT I've always seem to have a little bum steering but w/a bigger trailer now I really noticed it on a long trip I took this weekend. Looking for some suggestions on what could be causing it. Obviously less noticeable at lower speeds but at 55-65mph it really becomes more noticeable and having to keep my damn truck straight and in the center of the lane I'm driving in. Really drifts left and right and I'm fighting to keep my truck center.
Anyone experience something similar and if so what is the fix?
Thanks!

#1 Your E rated tires should carry a 80# psi cold for max payload.
#2 3,200# is the listed dry weight of your Raptor.
#3 The Raptor has a dry weight, of 13,600# and a GVWR of 16,500 that is a lot for an F250, any suspension mods.
Would your "Bum steering" bother you on a road like this, at the posted limit of 55mph or a little higher?? If not get it to a shop and get it figured out.

I agree Russ but Hankook MT's, 10plys Load E's in that size do have a max of 65 psi. according to their website.

On my f350 they were shot at about 90000 as I recall. I asked the shop why and he said well 2 years pulling a 5th wheel around and carrying a artic fox camper for another few. They do wear out, just alot faster when RVing.

I have always felt Ford steering boxes tend to do this. I have driven a few different Fords pulling a race car trailer and the same trailer with a couple different Chevys. The Chevy steering box feels "tighter" than Ford.
