Size choice

NooB to the Duramax world need advice on tire replacement on my '05 GMC dually. Factory eqip is 215/85/16, I'm concidering going up to 235/85/16 but I don't want to kill my fuel mi. or pulling power. the diff. in diameter is a little over an inch. For some reason the 235's are cheaper than 215 in the same tire. Has anyone done anything similar? thx
