I've got cross terrains and drive similar to you, and I have had absolutely no problem with them that I have noticed. I don't know however how much of this has been because of the 4R itself and how much becuase of the tire, but I have driven in lots of rain, snow, and ice, and some on gravel, dirt, mud, over trees and through brush and have never slipped or gotten stuck. I've also got 73K on the tires right now and they still are a long ways from the depth marker. The only reason that I would switch is if I were to get into more mud, but so far I haven't been able to. With my milage tendancy I really have to pay attention to length of life before off road benefits. How many miles are the Revo's lasting?
