Hi, I'm a new member, just joined, had my crossfire SRT6 about 2 months . I did my research for a spare tire for the crossfire, and I found one that fits all crossfires perfectly. It's a donut. It comes off an '04 SLK 500 Mercedes. The size of the donut tire is 155/70/17-inch. I have put it on the front and back of the crossfire - works perfectly. And it fits perfectly in the back luggage area where a tire is supposed to fit. It is the perfect height to work on both the front and back. You can call me the "Flat Tire God."

Cheers,
Jim.
