I picked up a set of 4 michelin xtour a/s 2 tires from Costco and i have no complaints so far. From what i've read and been told by others, they are basically rebranded defender 2s specifically for the wholesale club market, fir places like that of costco, bj's, and sams club, but don't take my word for it, as that is hear-say based on tread pattern and composition, ie Michelin will not openly say it. I was originally there to get cross climate 2s, but they were sold out nationwide (at costco) and only select stores had them, none of which were anywhere near me. Also, like someone above posted, they're directional tires, so i'm probably better off not having to babysit the techs to make sure they're rotated correctly.
My previous tires, bridgestone ecopias, came with the car, but they only lasted about 24k miles. While they needed to be changed any way since one of the tires already had two nails, I wouldn't recommend them, as i've seen numerous complaints specifically dealing with tread wear.
