I got an entire spare kit for a Challenger for $15.00. They are exactly the same for all Modern Mopars. Go to any pick-n-pull and get one out of a 06 Charger or what ever. I went on half priced day and it was $15.00 for the wheel, jack, foam insert.

I put it in, drove it around for a month with it. Took it out, bought a patch kit and a yearly subscription to AAA.
