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?

Eric, Tires have more than these two enemies, but they are big ones. Heat and age. (1) You are at the limit on the age of RV tires. (2) You just about have to assume that there was internal damage to that tire due to the tire running flat, which would generate a lot of heat. I have to vote to trash that tire. Might just save your life. Regards, G. Burke 1977 FC31SB Charlotte

The only information I can recall from a 'run flat' condition was that any tire that had lost as little as 40% of it's required pressure must be treated as a 'run flat' and dismounted for internal inspection.

Hi Eric

My thought is to replace the tire after any major loss of air, you will never know what damage may have occurred while driving.

Another concern would be the inside dual having to carry the extra weight.

If it would help,I can send sour cream money! (inside joke, folks)

Hi Fred,
Thanks for the advice. I'll have the inboard tire checked out while I'm at the
tire dealer's shop.

About that sour cream. It was a lot more expensive than I realized. I think it
came to around $600. Of course, I would accept a new Michelin 11R X 22.5 XZA3
for barter if you prefer!

See you folks down the road.

Hi Tim,

Thanks for your concern. To make you feel better (or maybe worse), let me share
that I got 11 trouble free years out of my last set of Michelins. Now I agree
that was probably too long, but how many years of life you get out of tires is
affected by a lot of variables.

The tire dealer believes tires that have been kept properly inflated, stored out
of the sun and get some regular usage can go 8-10 years. Nitrogen fill, which I
don't use, theoretically also helps. His advice is consistent with other
Michelin information I've read. These guys have every incentive to have us
change tires more frequently, so I believe their numbers are probably
conservative.

Our coach is stored inside and I follow inflation pressures closely. I think I
can safely use them another 2-4 years. I will replace this one that was run
flat and I may have to replace the other dual after inspection.

Your tire usage conditions may be quite different from mine and safe tire life
could be shorter. Although, even a new tire can fail, piece of mind is worth
something. At $600/tire, getting full, safe, use of a tire is also worth quite
a bit.

Thanks for your input.
