When combined with manufacturer and DT rebates, plus no-interest financing, I've never found a better deal at Costco over DT. I don't even shop around any longer...always just go to DT and they treat me right.

I've never had the MS2...but I had a set of A/T 2s on a 3/4 ton truck and they were fantastic. Plus they were warranted for 60k miles.

I just put a set of Goodyear Duratracs on my truck about 1200 miles ago. Great in the snow but pretty loud. I'll have to see how they wear on a heavy truck.
