I wanted to add, that my truck is lowered a fair amount in both front and rear. The top edge of the rear tires tuck under the fender, but are nowhere near hitting the top of the fender. I am running leaf springs front and rear. The shocks and springs are fairly stiff, with front and rear sway bars, and the only time I get rubbing, is when I am turning into a driveway. And even then, the only real issue, is that the tire squeals when it rubs. If I had a wider rim, the sidewall would bulge less, and therefore flex less, likely not rubbing. On a stock type setup, the body will roll much more, meaning a narrower tire is likely needed. Another thing to consider also, is that a larger diameter rim will use a lower profile tire, with much less sidewall flex. So I guess to some extent, the suspension setup matters a fair amount. Also Vegaskenn, there are some plastic type wheel tubs available that are about 2 inches if I remember correctly. I think that is what I will end up running......Mike
