I am closing in on purchasing a 2005 Limited Roadster with 8K miles on it. I am confused by some of the terminology surrounding the "run flat" capability of the car.

It seems that there are different types of run flat implementations on the market. Some tires come with the inner liner built into the tires, some implementations have the inner liner placed into the tire before it is mounted on the wheel and some seem to place the inner liner on the wheel itself.

If someone could help me understand how the run flat technology is implemented in the Crossfire, I would greatly appreciate it.

Having no spare, and getting a two inch gash in my tread that can't be fixed with the tire patch kit (This happened on the last trip I took) makes me nervous.


Thanks,
