Space Shuttle Tires
Name: C. R.
What are the tires of the space shuttle filled with,
and what keeps them from exploding in space?
Going into space is just like pumping an extra 14 pounds of pressure into the
tires -- not a serious problem. I don't actually know what the tires
are filled with, but I'd be very surprised if it's not air.
