The rims are MB Sparks:

and the tires are listed on the above post. Well... I did some driving today and I think I may have over reacted a little bit. There is definately some more road noise, but it's not that bad. A buddy of mine with a 5 series BMW has these tires. He's on his second set and according to him they "break in" in a couple hundred miles. I'm going back to have the lugs re-torqued on monday. I will find out if this noise is normal for these tires or if I can try to replace one or more if necessary.
The ride quality is exactly the same. The only difference is that when you hit a turn it handles substantialy better.
As far as the TPMS, they just transfered them from the factory rims to the new ones. I have the original set of wheels (minus the TPMS) sitting in my garage. I'm considering putting them in craigslist or ebay.
It's a shame... At the dealership the rims alone cost almost $400 per rim! The tires go for about $225 each. I'll be lucky if I can get $1100 for the whole set. If anyone is interested, let me know.
I'm going to take some more pics in the morning and post them. They really make the car look incredible.
