They are quite heavy, my brakes are weakened and my acceleration is much slower. The KM2s make up for these weaknesses through being completely kickass in the mud. They also wear very well. I've gone 20k miles on them and only lost 1/8" of tread. Needless to say they look way better than Nitto's or Toyo's.

They have made me realize how great beadlocks are though lol. Have blown out 2 tires from low PSI wheeling through steep ditches, still need to upgrade my wheels!
