The Flat Tire Monitor (FTM) system uses the ABS to measure each tire’s rolling radius changes and with it, the rotational speed of the wheels. Changes are detected and signaled as a flat tire. The FTM system does not use tire pressure sensors in the tires.

The Tire Pressure Monitor (TPM) system uses tire pressure sensors installed in the tires to check the tire inflation pressure in the four mounted tires. The system indicates if the tire inflation pressure has dropped considerably in one or several tires.
You are not wrong Jeff. We only get the rotational type down here.
