Ihave a 2008 420 rancher right now i'am running the stock wheels and tires i have a 2inch lift kit on it now .i'am going around in circles about wiether or not to just stay with the stock size or go + 1 or +2 in size . now as you all know honda did some thing goofy at least it is to me why would you run a 24x8-12 in the front and a 24x10-11 in the rear . i would think honda did that for the best of the machine . my other concern is power and strenght . going from a 24 to a 25 iwould think is not to bad but going from a 24 to a 26 would be kinda of so so in those two departments . the kinda of terrain i ride is fields of rocks hard pack some mud and of course snow . i would like some input . i would like the ground clearance though.
