I recently noticed that my trailer tires are wearing badly on the inside. I have a 2005 Lowe 180w with a Lowe trailer. I hadn't noticed them wearing on the inside until yesterday. One tire is almost bald and the other one has the steel belts showing through on the inside only, the rest of the tire is fine. The axle is steel tubing with the spindles welded on. I assumed the axle might be bent so I took the tires off and measured from the top of one spindle to the top of the other and then did the same thing on the bottom and both measurements came out the same. Just curious if anyone else has had this problem or what I might check to figure out the problem. Thanks
