08 & Aftermarket Wheels/Tires

I got mine from the dealer and all they did was take the ones out of the factory wheels and put them in the new wheels. They said they had to calibrate the sensors to the new wheels, and so far I've had no issues.

If you go to stores like Discount Tire, Big Rock etc etc they will charge you and extra fee to move these over... It is worth it, as of right now your only other option is to just listen the the chime for a couple minutes and then have that light lit up on your dash the whole time.
