I was taking a look at a gallery last night on this forum. I saw numerous Tundra DC just like mine with 2-6 inch lifts and really nice wheels and tires much larger than stock. With that in mind, none of the trucks in the gallery mention a gear upgrade. How big is too big? My ideal setup would be 2 inch lift in front with 17 inch wheels (MT Classic II) with a BFG AT that would fill up the tire well nicely. I saw one that looked really nice and he mentioned that he had 33's. That size tire has to mess with the speedo and gear ration, is this being ignored or is it not needed at all?
