The base of this post with be on tire size (hight and width) vs weight. I have a stock fj80 with the 3fe, stock gearing, living in south west arizona. I need new tires badly and would like a 33 but most of those are 12.5 and weigh about 55-60lbs. I am concerned that this amout of extra weight is goin to kill my already sluggish performance. Anyone with 33" wrangler mtr, cooper stt, km2 or the falkin wildpeak at. Please chime in. Aslo any other good tire suggestions.
