    What is the lowest PSI that can be run without triggering the TPMS with either stock tires or drag radials?

    If it is anything like previous Challengers, TPMS warning will kick in at 25 PSI and will go away once that particular tire has gone to 30 PSI or above. Since you should probably be running 18-20 PSI on DRs at the track you'll get the warning. Then air them back up and it should go away. :)
