Replaced the original 17" wheels and tires with new 18" Enkei AMMODO wheels, Continental LLR tires and new 315MHz TPMSs. Only problem, the TPMSs will not register. I can easily get the car in training mode for the TPMSs but the horn never chips on air release. I release air till the left front is almost flat then it times out and double chirps. I have a TPMS tool that I used on my 09 GT500. Supposedly should work on the Energi...but doesn't work either. Anyway to get them to register/train without taking the vehicle into a tire store? The TPMS fault light will come on after about 18-20 miles of continuous driving.
