The only cars that have "valve stems" are Base and SE models. Limiteds and SRTs have TPMS sensors with integrated "valve stems", I do not believe that exact replacement o-rings are available without spending $400 for a new set of compatible sensors, but you could call Rob at Needswings and see if he can source something suitable.

OR, just have a shop take the tire off, remove the TPMS sensor and toss it in the trash and have them install a new, actual valve stem - and just run without TPMS. My SE has never had TPMS, as I indicated above, nor does it have a steering wheel airbag.
