I know how he feels when you buy something this expensive and there are things wrong with it. Ours was the same way with issues as they all seem to be. No matter what the price you pay for your rig it has some issues to be worked out. I think the OP should talk to RVW and explain the tire issue also and they would hopefully warranty the tire/tires also. Good luck with it.
