have you accounted for the larger tires in your speed and distance traveled? Your speedometer is really counting revolutions of the output shaft on the transfer case. If you change any of the ratios after that point it will skew your speedometer and odometer. Larger tires means your rig will go farther per revolution of the tire making your mileage not quite as bad.
