That's good to know. I don't have any sway due to the Andersen WDH. My wife is uncomfortable with the squat of the already low profile tires. So, if I bring the tires up to 51psi while towing, it won't be an issue when the tires get hot and the psi rises?
Have you checked your payload? You are probably way over.
You need to get your truck weighed with a full tank of gas, and include anyone inside the truck. The stick is what it was when it left the factory with nothing else.
My payload with my wife and kids on my Limited is 437lbs if I recall.
Tire pressure is not going to change your a squat, that's your suspension.
It will change how much of the tire is hitting the ground, under inflated will wear the outsides, and over inflated will wear the middle, toeing exaggerates this.
