Flat tire

First trip as Full timers the wife and I went to a wonderful Music festival at Natural Chimney state park in Mount Solon Va. After much due diligence I felt pretty good about having the coach in good order. Parked the coach on Monday and on Sat when we started breaking down camp the two brand new tires I had installed on the front only two weeks ago were completely out of air. trying to add air even with a big compressor was unsuccessful on one of the tires as we were unable to get the tire to seat. Scared to death to have the coach towed on these roads so I guess i'm going to spend some big money to bring a repair truck to the park. What on earth could have caused the tires to go flat? What should I do to the tire that did pump back up to make sure it doesn't happen again?

I would think the shop who installed them didn't do it correctly.

Do you have a pressure monitor system on the tires?

Only flat I've ever had on a MH was due to one of mine leaking.

You should be able to get a tire store/ truck shop, to send someone to get you mobile . Keep your bills and go after the tire store that installed the tires , someone wasn't doing their job, of checking the bead seating or valve for leaks.
Do you have a pressure monitoring system ? Sometime those sensors fail and leave people stranded like this.

And I see a couple of other members type faster than I do.

I had a similar issue with new tires. On my coach when the tires were installed they used balancing powder. Quite some time later when checking the tire pressure the valve stem cores would not seal and allowed all of the air to escape. Upon pulling the cores you could see a build up on them. I replaced the cores, aired up and no problem since. Afterwards I found out when using the powder you're supposed to use special cores, which the truck tire shop obviously did not.

On the tire with a broken bead, the bead can be reseated using any flammable product. Search YouTube for "how to set a bead on a tire with fire". I saw it done 20 yrs ago at a Big O Tire shop with starting fluid. As for your other tire that you refilled with air, check the valve stem, either it's bad or maybe just loose, assuming you didn't run over a bunch of nails on your way to the music festival. Best of luck!

A truck mobile tire service will be able to get that tire bead reseated. I am in agreement with others regarding likely a valve stem problem.

Got an ERS?

Been there done that with 8 ft tractor tires on a log loader at a saw mill. What fun!!!

The odds of having TWO tires go flat at the same time is huge, especially on the same axle.

I'd suspect fowl play myself.

Jacking up the tire off the ground, hammering the tire thread, and providing air is many times successful in setting the bead.

I had a problem with a tire going down and it turned out to be the valve stem was not tight enough in the rim. Took a wrench and tighted it an no problem since.

Broken bead inside or out?

Put a racheting tiedown strap around the tire in the center of the tread, with the tire jacked up off the ground. If you can ratchet that tiedown enough, it will usually force the bead against the wheel, allowing it to seal enough to get pressure in. As the pressure builds, the bead will seat completely and you can remove the strap.

Disclaimer: This has worked for me for tires up to LT sizes; your motorhome tires may be too big and too stiff. But it's worth a shot.
