I mean, I guess you don't get mechanical grip for free. You aren't going to get full rated life out of tires if it is doing a good job at putting power to the road. I'm excited about the ability to rotate the tires, though.
It is always true that a well maintained car with higher miles is going to live a lot longer than a car with low miles that didn't receive proper maintenance. This becomes doubly true for the M3 because repairs and maintenance are very expensive! For crying out loud, it took 10w60 oil that cost >$20/qt and needed six quarts!
