the same way the coupe guys do there are no spare tire on the crossfire,,,,,,,,,,,,you would have to have two one for the front 25.1" tall and one for the rear 26" tall in the trunk if the car still has it you have a jack a air pump, a goop canister that will cost a lot of money when u use it as it screws up your tire pressure monitor and u have to buy a new one and that is not easy to find.
so the best thing to do is don't have a flat.
