I have an 04 tzx 190 and i have the same problem with my trailer. The outside of the right side tire wore out really quick so I put on the spare and it did the same thing. I am thinking about cutting the spindle off and straightening it up myself. By the time I realized there was a problem I'd had the boat about 1 1/2 years so I didn't think they would warranty it, but it sounds like there several people having the same problem.
