I can't speak for him but 275/70/17 or 275/65/18 will allow for a full sized spare where as 285 doesn't really... HB 4x4, aka Josh has a 285 spare but his tailpipe is different and I am not sure how that's workin for him. Last I knew he was having some rubbing. He's pretty active here, shoot him a PM for an update..
