After abusing the heck out of a set of Cooper Discoverer AT3's over almost 4000 miles of pavement, wet and dry, and punishing the tread and sidewalls on rocks in Utah and Colorado, I am sold on the Coopers as a solid AT tire.

I did not do a ton of mud with them, but they cleaned well with a blip of the throttle...it rained a lot the last few days in Moab, and we re-ran trails we had done earlier that changed a great deal with the rain...the mud unusual out there, it can have a solid crust on top that hides axle grease under it. The Coopers never stopped me, it was either ground clearance or good sense
