Depends on the actual system.
One type works of the ABS system. If it notices a wheel rotating at different speeds, it will trigger. So. If all tires are equal, but say, 8 pounds below recommended, you wont have the sendor trigger.
The best kind is the actual mounted on rim wheel sensor that can detect pressure changes. My guess is this one a) costs more money and b) would "go off" so much more frequently that drivers would ignore it.
