I have a 2006 Bass Tracker with a TrailStar trailer. It is a single tire trailer. Only has about 4000 miles on the tires. My problem is that the last 2 treads on the inside of the tire are worn down about 1/2 lower than the rest of the tire. Now that I have noticed it I had to drive all the way back to Indiana from Minnesota worrying about it. We made it okay and I spoke with a mechanic from Bass Pro shops who advised that it could run anywhere from $600-$1,500 to fix. Obviously he would have to look at it first. Has anyone had similar problems and what happened?
