NEW Dodge 2013 Ram 3500 4x4 -> ride is horrible! What to do?

TPMS is tire pressure monitoring system. At what point did you have the discussion with the salesman about the low tire indicator, was it during the test drive or after you signed the paperwork in the finance office? If it was before, then you should have had him air the tires to proper inflation and drive it before you made your decision.
