It's hard to choose which is the better tire. Both BFG KO2 and DuraTrac tires have the ability to perform quite decently on highways as well. The BFG KO2 triumphed when it came to maneuverability, particularly when it came to turning and cornering, even though Duratrac was still superior in terms of stopping distance.
Never had DT but I personally have been very is the ko2 I have. I drive pretty hard on the road and they handle really well for what they are. Since putting the SC in it they have handled the added power extremely well
