2012 TPMS on a 2009 R/T

I have a 2009 R/T Challenger that came with 18" wheels (P235/55R18).
I put 2012 Charger chrome 20" wheels and tires (P245/45R20) on with the 2012 factory sensors.

No tire light came on when I test drove it. A day later I let one tire down to 26 psi and drove it 2 miles and the light never came on, so I reinflated to 32 psi.


I used the DiabloSport InTune to reprogram the tire/wheel size (was less than 50 rpm at 55 mph).


Six weeks later as the fall cooler air moved in, my tire light came on. Tires were 29-30 psi, so I inflated all to 32 psi and after driving a couple hundred yards the light went off. So the 2012 sensors are now working on my 2009 R/T.

From other posts, I see the 2009 used the older sensors 56029400,
and the 2010 and newer used the sensors 56029398.
Anyone else having experience using the wrong sensor in a different year Challenger? I don't have the upgraded EVIC, just the base dash light.

The 2012 Charger wheels/tires I bought have the black/rubber valve stems 56029398AA ?

This site shows this,
Dodge Challenger TPMS Sensors
2008-2012 Dodge CHALLENGER-SRT TPMS Sensor OE Schrader 56029400AD 433MHz
2010-2012 Dodge CHALLENGER TPMS Sensor OE Schrader 56029398AA 433MHz

The detail page does show the non-SRT 2009 Challenger uses the same sensor (gray/metal stem) 56029400AD
2012 Challenger SRT8
2011 Challenger SRT8
2010 Challenger SRT8
2009 Challenger
