Hello folks, I have a 26 ft travel trailer. I use a weight distribution hitch. I have gotten some very uneven tire wear. I have a couple of tires that are wearing only on one half of the tire and mostly on the inside. I have other tires that are wearing in the middle tread more so than the outside tread. Any ideas of what might be causing this and best practices to correct?? I have been inflating to maximum tire inflation and these are the original tires (except the one that was showing metal and we replaced on the road). Thanks for the help.
