Flat Inner Dual Tire :-(

1) A nail caused the flat.
2) No, take it to a truck shop. The punk kids at Discount WILL damage your coach.

Without having the tire and wheel to examine, anything we say would be pure guess work. The flat could have been caused by anything from a nail in the tire to a loose or sticky valve stem to a rusty spot on the wheel bead seat. Or something else...

Is it still on your coach? If so, how are you going to take it anyplace ... A) take it off yourself, or B) have an ERS take it off for you.

If A), I'm curious - please let us know how that goes.

If B), FWIW - I dropped our ERS after decades because they refused to service a rear dual inner flat on our motorhome (the very reason I had their ERS for our motorhome!). What ERS do you have?

Is it as old as the coach?

Thanks for the responses.

Yes, the tire is as old as the coach. We're due for fresh tires.
We have both Good Sam and AAA for ERS. Since the RV is at home, I wonder if they would jack the RV, remove the tire, let me take it to get fixed, then come back and reinstall it. What do you think?

I'll keep you all updated on the repairs!

Rich,

FWIW, it's AAA that told me that their policy was not to service dual set inner tire flats ... so they said it was up to the technician they sent out whether or not it would be taken care of ... when our motorhome was sitting right in our own back yard! The technician arrived and agreed to try and service the inner flat. I helped the technician and we did get the inner tire changed.

I dropped AAA after that, as dual set inner rear tires represent one third of our motorhome's tires and I thought that a policy of not servicing them was unacceptable for a motorhome owner. What if this had happened out in the middle of nowhere and the AAA technician had refused to change the inner flat?

Just out of curiosity, was it the right side inner dual? A tire tech told our motorhome group that that is the most common tire failure with duals. Why? Driving off the edge of the paved road puts full load on the single tire. Eventually it had been over stressed enough.

Over the last 20 years we have had two flats, (one a blow out, one discovered when checking pressure before the trip) both were right side inner dual.

It was indeed the right side inner dual - had a nail in it - so the flat did not come from excessive load carrying.

I run with 80 lbs. in the rears all the time to make sure that they are always at their maximum loading carrying capacity, just in case. I have driven very slowly along the edge of a highway once on just one tire (the other was flat) of a rear dual set for around 5 miles. That drastically overloaded tire (Michelin) went on to give me several years of service.

Tire truck shop only...

Rich, if you have an air compressor, pull the units outside tire up onto a couple of 2x6's, this will take the pressure off the inner tire, then let it set for a while. The tires are stiff enough that they'll usually reset to the rim so that you can air the inner tire up if it doesn't have a massive leak. When you air the tire up remove the valve to allow more air flow to help reset the tire. If it'll hold air this will allow you to drive the unit to the nearest truck tire repair service.
