Tires - You may want to read this

Yahoo Message Number: 82999
This is just one of those FYI messages and it was totally my fault and ignorance on my part.
We stopped at one of the COE parks near Nashville for a few days while working our way back home.
Getting ready to leave the park I looked at my tires and the PS outside dual looked a bit low. I felt like I was leaning a bit for a few days of driving prior. At travel height I tested the distance from the top of the tire to the finder well with my fist and it was a little low. Checked pressure and had my usual of about 95 in the PS outside. Zero in the PS inside. Thumped the tire and sure enough, no air. That tire was also badly cupped and scraped and the PS outside showed signs of overheating.
I don't have any idea how long that tire was without air but could have easily been 500 miles or more. I think I put new tires on in March and only had about 6,000 miles on them.
My point is that the PS outside tire did not explode while handling all the weight of that side. That was for I don't know how many miles and at 65 mph Interstate speeds.
This is my second set of Michelin and I think I will stay with that brand. At the same time I will probably check them more often in the future. I am now no longer concerned if I need to drive some distance to a safe place with only one of the duals aired up.
The man above was looking down on me saying there is a lesson here son. Last four corner weight in 2010 indicated that the PS dual was 9750 lbs. Michelin must build in one heck of a safety factor. My luck and stupidity costed me about $1,500.

Richard - Thanks for the heads up and it's good to know your Michelin tires withstood abuse. Glad you didn't sustain severe damage and/or crash. We too have Michelin tires and use a Smartire system plus manually checking. Obvious question........ What caused the leak? Valve stem, valve insert, screw..........

Richard...........I put "Crossfire' units on my duals. Not only does it keep the pressure equalized between the duals, it has a visual indicator that makes a visual pressure check very easy at any time. Here's a link if you're interested:

Dave, how much was the CrossFire and did you install it yourself? John 03 Allure 30951

Valve stem. Aired it up and stayed at the COE park extra days. Drove the 800 miles home over a few days and stopped at times to look at the tires. Could not fine two of that size tires on the road and my dealer here stocks them. Supplies our fire truck and those boys are hard on tires.

You certainly did luck out !! There has been much testament to the Michelin tires, of which I am also a fan. On newer coaches , Smartire was installed, and this monitors tire pressure and temperature. I would highly suggest to get a pressure monitoring system for your coach. I think for a 6 tire system they are around 3 to 4 hundred dollars and as you can see , very worthwhile. If you had blown the outside tire a lot of damage , possibly to yourselves, as well as the coach. You might talk to a Michelin rep , to see if there is a possibility of damage , for having been overloaded for so long. Safe travels

I put them on 6 or 7 years ago. The install is pretty straightforward. They are pressure specific. I carry 110 PSI in the rears and that is what mine are set up for. Another nice thing is that, once installed, you have a single, very accessible valve to top off the rears. No more need to fool around with a pressue guage. They are on e-Bay among other places:

Thanks Ron,

Did not want to take a chance with an abused tire so replaced both.

I'm 100% sold on tire pressure monitoring. I had FOUR leaking valve stems last year (from a well-known coach tire dealer that didn't properly tighten my new steel valve stems that I had installed all around when I replaced my two front tires), and one months-old trailer tire with a failed sidewall, all of which I caught before anything bad happened, because of tire pressure monitoring. My morning routine is now to turn the ignition on to start picking up the tire sensors, then do my walkaround, then look at my dash at all the pressure readings, so I don't need to get the gauge out and take off valve caps etc. unless I need to actually add air.
If anyone needs tire monitoring, I have a like-new TST pressure & temperature monitoring system (the new 510 monitors) for 12 tires (coach w/ tag plus toad/trailer, with extender) that I installed and tested (in driveway), but never took on road, as I did a Silverleaf conversion with integrated PressurePro monitoring.
The TST has better functionality (esp w/ temperature monitoring, and much more control over the alarm setpoints), which is why I bought it in the first place after extensive research, but the Silverleaf PressurePro integration is nice (messages integrated with existing warning/errors, etc). Either is of course much superior to nothing.

Will sell for 40% less than I paid for it.

SmarTire II has all the TST functionality. Batteries are still available.

Tire failures are not uncommon caused from road hazards Using CrossFire, aren't you increasing the convenience of filling at the sacrifice of safety? If one tire blows, I hope my still inflated dual mate tire will keep me afloat, at least long enough to make a safe landing.

Seems like equalizing pressure in both tires would cause both tires to deflate if a puncture occurred in one of them.

Check valves in the Crossfire device will immediately close when either tire deflates...............maintaining full pressure in the remaining good tire.

Thank you for straightening me out on how CrossFire functions! Sounds like a good system.
