+1 on the Cooper ATR's. I put them on my truck November 2005 and love them. Very quite and they give very good traction in the snow and on wet roads. Most of the time I will run around in 2 wheel with snow on the roads with very little slipping and spinning (I also have 4 tube sand bags in the bed). I had originally planned on putting Revo's on.... but for $200 more I just could not justify the cost.

FYI- I had prior to the ATR's the Discoverer AT's which worked well, but they are no longer made. The AT's are similar to the Discoverer HT's that are available. Good luck with your search
