I just put on a set of 275/30-19's yesterday. The tire guys kept cussing at me and ended up charging me 100 bucks to put them on because, I quote, "those were a son of a ***** to put on" They look great and they ride great too. I was going to go with 285's but if the tire guys had that much trouble, afraid they would not be able to put on the 285's.
