    I understand the factory tires on our Cats are equipped with TPMS sensors.

    My question is: what kind of problem (if any) would I run into if I were to install 2 Mickey Thompson tires on the rears with just plain valve stems?

    Thank you !

    You are going to get a low tire pressure warning...not sure if the HC is the same but my 2013 SRT would flash the warning on the EVIC along with an audible warning that drove me nuts....I had the tuner turn them off since I track the car often with DRs..

    I can see where that would be a PITA ! ----- so if I have OEM sensors P/N 56029400AE installed will I have to go back to the dealer to have them programmed or can they be set by the tire store doing the mounting?

    The sensors calibrate themselves after a mile or so.

    I got my new wheels with new sensors on today and drove across town and back and they have not calibrated. Seems one might be reading, but 3 show --. Does it take more time? Should I air out or air up to get it to register?

    I've heard of several of several sensors that come malfunctioning or in storage mode for the battery. The tire shops have a tool that "wakes" up the sensor. At least that's they way it worked on my Subaru STI. Maybe they missed that one sensor or it could be DOA. When I switch wheels mine always picks up the new tires immediately within a few minutes.

    Sometimes they take a little while to update. Drive it one more time and see what happens.

    I have heard that there is a mode for snow tires. But not sure if it will work with just 2 missing. Supposedly if your missing all 4 TPMS sensors you can OK the system to reset it and no further lights/alarms. Then when it SEES Sensors again it will start working again.

    These cars are plug and play. If you mount new tires with new sensors it will sort things out in a few miles. Just think what it is like when you put her away after being driven hard. The next morning when you drive away some or all the pressures are still reading the higher pressures for a few miles until they update. Some being slower than others.



    I switch back and forth between my Drag setup and street setup all the time with no issues whatsoever.
