We've owned a pair of Chargers and three Challengers. The earlier ones had jacks and spares. Current ones not. If the speare tire well on my Challenger didn't have speakers in it, I'd buy a spare/jack. Anyway, how often has anyone been stuck somewhere with a tire issue/blowout that could not have been solved with the "aerosol" stuff? We've never had a flat on any of our cars, but we do take a few longer trips. Can't imagine what a pain in the a$$/pocketbook it would be to lose a tire halfway between San Diego and Phoenix.
