It wasn't the tire pressure, but the compartment where the tires are located. The heat sensor went off, which could mean the missing tiles allowed heat to get into the interior areas.

I disagree... The "off scale low" does not mean low pressure. It could, just as easily, have meant no reading... cause by a off scale high reading that was not temetered.

I did not mean to sound like an expert, that is what I heard described on the radio today. I'm sure there are people here with more knowledge of these things than I. Either way, that was the area they'd noticed before all the sensors on the left side went out.

No, I don't think that "off-scale low" can be interpreted as being a possible indication of "off-scale high". Any reasonable instrumentation system can distinguish between the two conditions. Certainly, the interpretation placed on the "off-scal low" indication at the 3:30 EST press conference was that instrumentation had failed.
