Photos of the tires on one of the rear tandem trailer axle after approximately 5,000 miles of level towing. Photo of the wheels on level ground. Notice the wheels on the second axle at an odd camber. The front axle isn't right either, though not as bad, and its tires are needing to be replaced after 10,000 miles because of uneven wear. User's recommendation: Don’t buy a Shadow Cruiser or Heartland trailer because of their lousy customer service.
