Tire problems in Texarkana area . outside wear issues

The passenger side wheels on RV's are more likely to hit curbs and obstructions than the drivers side. When the wheel or tire smacks a curb while turning right, the spindle can be bent, and it doesn't take a much to bend a spindle.

Once the spindle is bent, the tire is mis-aligned, and then you get tire wear like you describe.

When you take it in to have it checked, also have the shop check the hangers, bushing and bolts for wear and tear. Might be a good time to have wet bolts and bronze bushing installed.
