Should I Replace a Rear Tire Run Flat?

[bberic35]

Stopped by the road to check everything on way back from Albuquerque rally and
found my left rear outside tire was flat. Don't know how long it had run that
way. Luckily, I jacked the coach up and put air to it and got it to reseat on
the rim and pumped it up to normal pressure of 100 psi. In the process, I found
the source of the leak was a loose Cross Fire hose connection on the tire stem.
Drove another 300 miles without incident.

I can't see any visible damage to tire sidewall, but am concerned there may be
internal damage I can't see. Thinking I might do well to replace the tire just
to be safe. It's a six year old tire.

Any thoughts?
