The free towing from D/C works as advertised.

You call the 800 number, give them some of the info from your car, and they call around to get you a tow. I only waited about 45 minutes from the time I called until the tow truck pulled up. Actually, it was a small car carrier. I don't think you are supposed to tow a Crossfire.

And I also think I will consider run flats for my next set of tires, asuming they are available in 18" fronts and 19" rears...
