I have a 5th wheel with about 6,000 miles total on the trailer. I noticed today that I have two tires wearing on the inside. It is the driver rear and the passenger front. The other tires look new and the outside of the ones that are wearing look new the inside are about bald. Can I rotate these so the tires will get a little more miles or do I need to replace them. If they were car tires I wold not replace. Also if I replace them how can I prevent this.
Thanks Tom

Don't rotate the tires...take the trailer back to where you bought it and have them check it out it could be just loose bearing retaining nuts. If it is the axles then they will have to fix the problem

It sounds like you have severe axle misalignment. If it is still under warranty, take it back to the dealer & get the wheels aligned. If your warranty is up, get it done yourself at any shop that aligns trucks. It is only about a $100 job, cheaper than future tires.
