RFT's are a major nightmare. Call the dealership and ask them how much are replacements and if they have them in stock. If they can't help you right away..you may want to reevaluate your purchase.
My wife had RFT's on her car and I had regulars on mine. We had a vandal go through the neighborhood one night and puncture multiple tires on lots of cars. This was Friday. My car was up and running within 24 hours. My wife couldn't get replacement RFTs for several days (they were Continentals so well known company).
I had an X3 and she a Mini cooper. One of the major reasons I did not buy a new X3 was because of their RFT only set ups.
