I imagine some here who tow a vehicle can relate to this.
We have odd front tire wear on our tow vehicle, our 2006 Jeep Liberty, caused when making sharp turns with the motorhome. The only solution is to avoid making sharp turns, most especially from sharp this-way to immediate sharp that-way, but it also happens when going straight, then into a sharp turn.
This is the type of tire wear happening on the tow vehicle front tires.
This is NOT a front wheel "alignment" issue. The wear is caused because the tow vehicle steering wheel cannot react fast enough to the quick change in direction when being pulled.
The rear overhang of the motorhome amplifies the condition. The need for a tow bar riser makes it worse yet. All is well when going straight or taking on gradual curves and turns, but the issue as one given example is when your PC makes a sharp turn to the left, it's tail swings right. So the tow vehicle starts to follow going right, then suddenly has to make a very sharp left. The tow vehicle's front tires then briefly get dragged sideways across the pavement until it's steering wheel catches up with the quick change in direction.
The only thing I can see helping is to have a tow vehicle that does not require a riser to "level" the tow bar. We towed a little Toyota MR2 Spyder which did not require a tow bar riser and it did not have this odd tire wear. Maybe the steering wheel on that little car also reacted faster.
I have two sets of tires (with wheels) for our Liberty. One set is dedicated for home use, the other for trips. I rotate the trip tires to get more use from them but I always have to replace them prematurely.
My neighbor with a huge diesel pusher towing a Chevy SUV has the save exact issue as we do, so I know we are not alone.
So........
Keep this in-mind when selecting a tow vehicle.
