Anybody ever have a flat in their Hellcat yet, and have to use the factory inflator kit? Just wondering how well they work and how reliable they may be. I am old school and still did not like the fact that I'm driving around with no actual spare tire. I have heard they may work for a very small puncture, but anything too large and you are SOL. Also, if you had no cell reception to call for help, with the SOS button in the mirror work? I had heard that runs off of GPS. Thanks!
