i know you could get away with a 2" spacer. im running pretty much the same setup there, i have a 2" spacer with 315's and have no rubbing issues, and yes i agree it looks sick and makes it look like a 4x4 truck.

I went with EGR flares, they cover about two inches which is about what I needed after the 315's and the two inch spacers. I thought they looked a little squirrelly with so much tire sticking out. IMO anyway, but different strokes for different folks. :cool:

In the pic, the tires look like they still stick out past the flares, but looking straight down the truck they cover them for the most part.

Anything less than a 2" and you have to cut your lugs off.
