1-30-2010 - Turbo on a donut?

After playing with the BOV the night before, the TPMS light came on all of a sudden. I checked the tires and found a huge crack in the sidewall of the front driver's side tire. So it's off to the dealer for a new OEM tire. Lame because they are SO expensive, but I have so few miles on the tires I just can't justify buying 4 new ones right now.
