The TPM malfunction is different from a flat tire. The malfunction is a failure of the entire system (for whatever reason), where a flat tire will actually cause the TPMS to indicate a flat tire warning and will show you which tire is flat.
As for the flat tire, it would have to be pretty warm out, or you would have to put A LOT of heat into those tires, to make the air warm enough to expend the tire off rim (an F1 car could maybe do it). *Caution-Physics imminent* More than likely what you're referring to is the centrifugal force applied by the rotational inertia of the wheel itself pushing the tire against the pavement resulting in rim being lifted off the ground (Equal and opposite reaction).
