You could be right about the 220 psi, the space shuttle tyres are 340 psi.

"Surprisingly, a space shuttle tire is not much larger than a truck tire,
but a main landing gear tire can carry three times the load of a Boeing 747
tire or the entire starting line-up of a NASCAR race -- 40 race cars - "
I guess basically the bigger the tyres the lower the pressure.
Mind you the combinaation of the high rotational speed and high pressures
might be quite dangerous, as some concorde passangers found out.
I am not sure if it is the speed of rotation or the pressure which is most
to
blame, maybe a combination of both.
220 psi is some force.

"The tire/wheel assembly exploded, tearing the hub into two pieces. One
piece bounced off a railing, hitting one helper in the head, killing him
instantly. His body was found 10 feet from the spot where he had been
standing. The other portion of the hub struck the crew chief with so much
force that he was thrown some 30 feet. His head and right arm were severed
from his body. All of the wheel bolts were found bent...and the threads on
five bolts were stripped. Only four of the wheel nuts were found."
Anyhow if aircraft tires were inflated to 27psi, (as I thought reasonable)
concorde might still be flying today!!
I guess there is no profit in transporting lots of tires though!!
