I'm in the same boat as Rob, the Dueler Alenza's are not a poor performer as of yet and for once I'm "pleased" with the factory offerings on a truck. With that said, I do miss my LTX M/S2s that were on the 2006. I had 40k miles on those tires and at least 1/3-1/2 life remaining. They are stellar, let me repeat, stellar tires. I wish they looked a little more aggressive on the sidewalls though, similar to the Toyo Open Country AT2.
