Title: Shuttle question.
Post by: BILLR on December 27, 2012, 09:43:36 PM

Hi guys. I have a question about the tires on the space shuttle. Were the tires inflated for the whole flight , from launch until landing, or were they inflated at some point before landing after re-entry.I ask this question because i noted one of the call's for Columbia was a tire pressure loss on re-entry during the accident. I assume the tires would not be infated until the final phases of flight do to the hugh pressure and temperature changes. Thanks.

Shuttle tires were kept inflated for the whole flight.  The pressure difference between orbit and sea level is only 15 PSI, a difference that most tires can cope with.  For instance, your car's tires recommend around 30 PSI but can probably take 60 (although I wouldn't want to try it myself).
