There is no one around my area that does alignment on trailer axles. I spoke with a guy at the local RV dealer and he said they just ordered need axles. Mine were replaced 18 months ago, the old ones were wearing my tires also. The guy at the shop said the tires I had were junk and that was the biggest part of my problem. I think I will just replace the tires with a better set of 14's and keep a close watch on the wear. If I start to see excessive wear on good tires I'll try something different. Now to decide on the tire brand.
