These original GM C6 Corvette Tire Pressure Sensors, with built-in valve stem, deliver real time tire pressure information to the driver. When a tire is losing pressure, the C6 Corvette Tire Pressure Monitoring System provides an early warning. Working C6 Corvette Tire Pressure Sensors are especially important with the extended mobility tires that come standard on the C6. The EMT tires are great but as a driver you can never tell when they are losing pressure.
