After reading through the thread, recalled a couple of other things worth noting...
I also had the break squeal mentioned by a couple. Started around 10k miles, had it troubleshot by a local dealer, who replaced the pads with a good amount of anti-squeal grease. Squeal came back about 5k miles later and remained an intermittent issue through about 25k miles. The squeal was gone for good at that point, with roughly 15k miles on that set of OEM pads.
Regarding tire wear... Change the original tires at 25k miles, prior to putting the car up for sale, wanted the next owner to at least have a couple/few years before incurring that bill. The OEM Michelins still had a decent amount of tread as well, probably another 3-4k of life left in them I'm guessing. They were replaced with OEM (on the Z51) Michelins.
A'Hui hou all,
