The shuttle is launched with the tires uninflated, if I am not mistaken.

Some questions....

At what point in the re-entry process are they re-inflated, relative to the shuttle's re-entry timeline?

I am not clear if the tires had already been re-inflated when the loss occurred of vehicle.

Is it after falling below so many hundred thousand feet or 8-?

Does this process and its initiation ever vary?

What type of mechanism/mechinery is used and how is the process initiated, etc?

Any pyros involved in opening the wheel doors?

I previously seached the net for the answer to this very question. Never found the answer. The tires are inflated to about 300 psi and rated to 900 psi. They are only used for one or two landings.
