I am looking at doing the same thing with my truck. Are you upsizing your tires? I was also looking at the revo's and BFG's but the Firestones look like a better deal to me because of the good ratings I have seen on them. I am looking at going from crap Dunlop 265/65-17 to Firestone Destination AT 265/70-17's unless someone can convience me that revo's or BFG's are that much better then those tires.
