The tire that you cannot inflate, needs the valve stem unscrewed a little bit, maybe half of a turn. The valve stem sits to low in the valve and is not properly activated when the airchuck pushes on the stem,and this is why your pressure sensor reeds low pressure because the stem does not let enough air out for a proper reading.
It reads fine. I have tried that, the valve simply will not let air pass through to fill. I think the same valve is leaking. It's not the TST reporting falsely low PSI, it is low. I think the TST is causing it to leak. It's a bad sensor.
