A good place to see some reference on the different tires is at Tirerack.com. They have ratings and comparisons on many of the major brands for all different varieties of tires. I have had alot of tires over the years, but on my trucks I have for years now been using Michelin LTX M/S, in the original, the second generation and the newest generation Defender series. I have been really happy with all of them and found they not only drove well in all conditions, but wear well. When my current set of LTX AT2 (Original tires on my current truck) finally wear out I will switch to the Defender LTX M/S.
