I know all you hear about on the forums is Duratracs but it's for a reason. They are really great. Lighter than the nittos, very aggressive looking, relatively quiet, and great on/off road. I love mine.

I am not biased one way or the other. I am running Fuel Mud Gripper 35x13.50x20 (Open Country MT knock-off) and have to admit that it is one of the worst tires I have ran. I have owned a set of Open Country MT and although they weren't the best they were better than the Fuels. Now if you would like to buy my set of 5 so I can move to some 37x13.50 20 Kuhmo Road Venture MT's I recant my last statement and let's talk business.
Everyone has their own opinion but seeing the KO2 on my JK was more convincing of how aggressive they look than seeing pics of them online. The tread is 15/32 and I think the Duratrac is 17/32. I was considering the KO2 34x10.50r17, Duratrac 315/70/17 and Exo Grappler 315/70/17. I didn't want really wide tires but wanted height. I'm happy with what I have now.
Assuming you are buying these for mostly on-road, I had a set of 32's on my TJ and liked them. They got clogged with mud easily, didn't care for that. I used them in Moab and they held up. They were just 'OK' in the wet, I think the Duratrac's are reported to be better in rain.
