I'm running 32" tires. Switching to 4.10's put the shift points back to what they were when I was running stock size tires. Having the shift points back where they were means running at 1600-1800 rpm at 45 and 55 again which will save fuel. The heavier you make it the more fuel you will use to get it all rolling. Not much you can do about that.
