Don't worry about the weight so much, everything weights more than the stockers. Maxxis Bighorns are heavier than most, the 26" of the Bighorns weight 1.5 lbs more than the 27" ITP Mud Lites. Bighorns are not nearly as good in the mud, but are great for "true" rockcrawlin, but who on here is really doing that? For trailriding on mountains I would say its a toss-up.
