A year or so ago, we too lost a wheel due to sheared lug studs. Ours departed the rig while traveling 55 to 60 mph. Temp and pressure readings remained unchanged since the prior reading since there was no sensor to read from. HOWEVER we did get a single chirp warning that something untoward had happened. We were scratching our heads trying to make sense of what had transpired when another pickup came flying up behind us traveling triple digits and braked hard beside us to flag us down. He had been following us and had stopped to retrieve the errant tire / wheel.

So yes - this is another example of the unexpected with our TPMS which happens to also be a TST. Speaking with a TST engineer after the fact, he deduced that when a sensor departs a trailer in motion, the software is written to display the last known values. With that said, from a technological standpoint I'm at a loss as to why a sensor would not indicate zero psi shortly after a catastrophic blowout UNLESS the sensor was also damaged. If that indeed happened, the sensor could not have provided updated data.,
