Gigster...are you saying that the tire doesn't fit on the tire mount or won't fit in the recess in the fender? If mounting assem.you have is for a 3/4 or 1-ton, the mounting studs will be too far apart for your wheel to go on. If that's the case, I have a 1/2 ton assem.& need a 3/4 -1 ton assem. we could trade.
