Truck tires vs RV tires on a Class A

I third that Toyo tires are excellent tires for coaches. Country Coach used them on their Coaches for some years. And I would rather have that h rating and not worry about zipper blow outs that Michelin had with their XRV tires.

I have had both on my coach and it rides smooth with either, no difference.

As to the cupping mentioned, that is not a tire problem,it is a problem with tire bounce caused by worn components, probably shocks.
