If there was a loss of thermal protection over the gear doors, you could have a compromise of the tire pressure because of the relationship between temperature and pressure.

If the PLT or CDR noted a tire pressure gauge reading changing, it may be an indication of loss of integrity of the heat shield.

Interesting stuff here. So if the heart shield is compromised, then obviously it can not be corrected by computers or crew.
