In the U.S., if you purchased a car or light duty vehicle under 10,000 lbs, manufactured after September 1, 2007, you have TPMS. If your model was manufactured after October 5, 2005, you might  have TPMS. Also, prior to the legislation, some higher-end vehicles also came equipped with TPMS as a premium option. Among other matters, within TREAD Act of 2000, the U.S. federal government mandated the required implementation of TPMS on all new vehicles in the following phased rollout:

• 20% of new vehicles from Oct 5, 2005–Aug 31, 2006
• 70% of new vehicles from Sept 1, 2006–Aug 31, 2007
• 100% of new vehicles from Sept 1, 2007 and beyond

There are several ways to determine if your vehicle is equipped with TPMS. The easiest include checking the owner's manual and watching the dashboard indicator lights at startup. Turn the vehicle ignition switch to the "ON" or "AUX" position, or simply start the vehicle. Look for a TPMS warning light on the dashboard ( ! ).
