Well we got to test the Run Flat Tires. The car picked up a 4 inch nail on the way to work (through the sidewall, so the tire is trashed). Me being the rocket scientist that I am pulled it and the tire lost all air pressure. Drove it home on the flat tire (32 miles) then to the dealer (40 miles). Not into this Run Flat concept, but it works. Sorry BMW but we ran the car at 70 MPH (vice the recommended 50 on a flat tire). Still love this car.
