Over pressure can absolutely cause bad wandering. Our MH had 115 psi in the steer tires when we picked it up from the dealer. It was like trying to wrestle a bull driving it. After a weighing and determining the psi should be set at 85, everything settled down.
So as instructed the tires were set "cold" as they're suppose to be per the weight the rig is running at.
Now ours does have a constant pull to the right which I haven't been able to get figured out. Supposedly the alignment is correct and I have new shocks and tires are set properly. I think a blue ox Tru center in in our future.
Most all roads have a crown so your right hand side is almost always downhill from your left hand side. Doesn't affect cars a lot, but can have more of an effect on motorhomes.
I have considered this and put myself in the far left lane on the freeway. So technically it should pull the opposite way. It takes most out of the pull out, but a left correction is still needed.
You say new tires. Did it start with the new tires, or been consistent thru a couple sets of tires? Tires can have a belt go bad. I have had several on my semi front tires over the years go bad. When they do, it starts pulling to one side or the other.
You could try swapping the left front tire to the right side, and visa versa. Does the pull swap sides? If it does, it is a tire. If so, the bad tire is the one OPPOSITE the way it is pulling.
Might be your problem. Might not. If not, go to a good, heavy duty truck alignment center. They should be able to figure it out.
