Two Sets of Wheels? Get Two Sets of TPMS Sensors!
Tire Pressure Monitoring System sensors (TPMS sensors) have been around since the 1980s, but only became a legal requirement on vehicles sold in the United States since the 2008 model year. They're an integrated part of tire valve stems, with built-in batteries and sensors that sit on the inner edge of the wheel concealed within the tire.
