I was trying to find some recent info on tires for my TM and/or TV when I found this link which although not specific to trailer tires does give a pretty good idea of just how many complaints a particular tire company or brand gets relative to others.
For the TM, I am thinking that I will go with MAXXIS tires from Amazon with local mounting. Interestingly, this link shows NO complaints about MAXXIS that I can find.
