you'll be happy with the coopers, i ran them for about a year before needing mud terrains. after 10,000 miles i sold the set for a little over 300 and paybe about 640 for all four brand new. they looked a little under half life tread at 10,000. When i first mounted them they were extremely quiet but after about 8,000 they grew a little louder but IMO great All terrain tire. two winters ago we had a real heavy ice storm me and some buddies road down from monroe NC to chesterfeild SC to play in the ice an snow with there jeeps. its about about a 45 minute ride, anyways we got out there (ran about 45-60mph on the road to get ther) played around offroad, then drove back, my buddy michael had a blow out in his jeep on the way home. the jeep slid over into the opposite lane mike held on to it got it sliding back the other way and got it stoped (in the right lane lol) once everyone got stoped to help him out. we all steped out of our trucks about the same time and everyone of us busted our ass's on the ice as soon as we steped out. evidently we had been driving on about an inch thick piece of ice completely blanketing the road. True testiment to the cooper all terain i ran about 55mph the hole way there and back didnt spin, slip slide once(other than intentionally around corners), didnt even know i was driving on ice!
