Have a 2016 enclosed Triton 12 ft trailer for two sleds which I had purchased new. While coming back from Togwotee in 2020 at a gas stop I noticed one tire was shredded, one side of the tread was down to the cord the other side had only a small amount of tread left. Obviously the tire was not tracking straight causing the abnormal wear. So I consulted a dealer that specialized only in trailer sales. He advised that Triton had used a light capacity rubber torsion axel,( 2200lbs), which was border line too light for the load. It had lasted only 4 yrs and about 10-12 trips. I now have a 3600lb axel. Hoping this cures the problem. Also if you store your sleds on the trailer you should jack up the trailer as to relieve the load on the rubber torsion material as they can be crushed over time, I didn't know this so I may have contributed to the axel failure.
