I'll go through my tire experiences, only including tires I have purchased new, not the numerous used tires I have had:
BFG Mud's circa 2001. 33x12.5x15's. Tires had decent traction, thinner side walls made for a smoother ride, but were weaker for the trail. When they hit 50k miles, the tread was so hard, they were downright scary on the highway. I ran the prototype KM2's, and really liked how much better they were, but have yet to drive the updated production tread design.
BFG All terrain KO's. 2006-2008. Sizes 265x75x16, 285x75x16, and 285x75x17. The 17's were a bit taller. After 40-45k miles, the tread became very hard, almost useless. When new, the traction was great in everything but mud. Loved the tires, and would buy another set in a heartbeat. Only killed 1 sidewall wheeling them every weekend.
Goodyear MTR. 2000. 35x12.5x15. Great traction throughout their tread life. The stiff sidewall caused a rougher ride, and also necessitated airing down to 7-9psi to perform similar to a BFG mud at 12-14. Loved the tires, although were baldly balanced from new (16 oz out per tire). Ran the tires until 2009, when bald, after being on 2 vehicles. Would buy again any day.
Pro Comp Xterrain. 2002. 35x12.5x15. Great on highway traction. Good road ride. Would not hook up worth a damn on the rocks, especially wet rocks. The thick tread did not want to conform. After 2 months of ownership, I sold the tires.
Dunlop Rover AT. 2004 and 2005. 33x12.5x15. OK highway traction. Sliced a sidewall open on a curb in front of my house. Lasted 25k miles till bald. Would never buy again.
Bridgestone AT REVO 265x70x16. 2007. Good highway traction. Wearing much faster than expected. Should have put on BFG all terrains.
Mickey Thompson Baja MTZ. 2008. 35x12.5x15. Great highway traction. Great traction on the trail. Better than MTR. Sidewall is thinner, but holding up so far. About 3k miles on them at this point, with one trip through the rubicon. Unbalanced, they ride smoother than the MTR's balances. So far, very impressed by their performance.
