As is with the larger tires 5th gear acts more like an over drive for 45-55 mph. Otherwise I find I need to go to 4th when the going get tough.
The idea in the stock configuration of tires was to switch out the ring and diff gears in the car for a higher ratio, then when you wanted lower ratios shift to 4wd low.
I havent driven the kick that much. My tacoma I had I did 10 thousand miles. When it was raining or slick out I shifted to 4wd with no problems, then back to 2wd in parking lots.
