I will be shocked if I don't get to 50 or 60k. I'm almost to 40 right now and I've got plenty of tread left. Rotations are the name of the game and I have mine rotated every oil change. I have always done that with every vehicle I have ever owned and haven't had any short life tires like so many people complain of and I have owned many many brands and sizes.
Yup... I'm shocked as well. I had a MB ML500, that needed tires every 15-18k. So yes, shocked is an understatement when I got these numbers.
I got an AMAZING 50k out of my OEMs (20inch) tires... purchased the same brand, as the Michelin's were to expensive in my opinion. They might be a little noisier than Michelin's, but they held up pretty well in my book.
We had a ton of snow last week, and the "Beast" held up fine, while other cars/trucks were spinning out all over the place.
