I have set of Cooper SST Pro's on a 3500 DRW. Pretty aggressive tire, but it is lasting surprisingly well. Great off road traction as you would expect with that type of tread. I have had good luck with Hankook ATM long lasting middle of the road all terrain type tire. I am also happy with Nitto G2 and EXO Grappler. The G2 really good traction on wet and icy roads, but it is a quiet tire and is also holding up very well. The EXO is more like the Cooper, more noisy but much more aggressive. I am on my third set of EXO's on a SRW 3500.
