hahaha..I thought you were referring to Tire and Wheel and how they handled this situation! I'm going to contact Chrysler Corporate Office tommorrow in hopes of talking to someone who actually knows what they are talking about since everyone including the local dealer has a different take on how they work when you've replaced them. I don't know if there's some reason it's not reading correctly after relplacing the back two tpms b/c all four used to read correclty. Would lyou thnk with 13.5 psi the tire would look lower or differnt than the other ones? It didn't. I know when I took the car into a local place to do something with it, they told me that the one back tiire was reading low, but I've never seen that and I' was checking it pretty regularly. Crossifre is a unique and strange thing but I love it anyway. I just wanted to have a cool sports car that people thought I looked great driving and have fun in...little did I know.........what a challenge the car would become.
