    With that tire size, 4.56 will be great to give more power for city and off-road driving. On the highway in overdrive, you will probably notice an MPG drop with the engine revving a little higher at cruising speed. 4.10 gears should restore the stock power band and keep the MPG's closer to stock on the highway.

    I know guys with 285's and 4.56 gears that are happy with the power, and I know others are happy with taller 35" tires and the highway MPG's with 4.56 gears.

    You don't NEED to upgrade gears.
