I really like the Mudlites. You may also want to comparison shop with them. They are a very aggressive tire and they also wear surprisingly well. As mentioned, they ride a little rough on pavement at slow speeds, but they really get great traction. The other thing one must keep in mind is to not get too aggressive with the lift and such. It can affect both steering and handling. Knock on wood, I have had no issues with breakage despite my aggressive tires and the machine's ample weight.
