I have a '90 Prostar 190 that I trailer quite a bit. I have been having problems with tires blowing out on the highway and decided that there was just too much weight on those little 14" tires once my boat was loaded with skis, boom, pylon, etc. I read a thread here last year about someone upgrading to 15" wheels/tires, so I did it. The thread said that they just added a 1" shim on top of the axle; I did this, and I have plenty of clearance between the top of the tire and the fender, but the inside side of the tire has very little clearance when stationary, and when I bounce the trailer it rubs. It also appears that one side has more clearance than the other. It looks like if I modified the fenders I could make it work, but I would really rather not do that... does anyone have any suggestions?
