One of the highest rated tires to come along in a long time.
TRAIL GRAPPLER M/T - OnlineTires.com
I really like the Cooper Discoverer STT.
Other tires of note are Goodyear Wrangler Duratrac (variants include Kelly Safari TSR and Fierce Attitude), Goodyear Wrangler MTR/kevlar, and all of the Cooper "Jeep boutique" tires ---- Dick Cepek, Micky Thompson, and ProComp.
When 4WheelParts runs a sale, you can get the ProComps for a song. They get badmouthed often for no real reason; ProComps are the same as the other Cooper tires and do fine.
