Title: Tire blowouts at 25000 miles - Michelin LT 225/75R16.
Post by: chrisawyer on May 20, 2013, 08:01:23 pm
I had a tire blow out on Friday May 17th and 150 miles later a second tire blew. The treads separated from the casing in each case. Michelin will partly compensate on tread depth, 9/32nd., but not interested in checking the other five tires. The tires are original on the Ford chassis, now a 2011, PC 2700.
Have any other PC owners had these tire problems?
Chris.

I have not had any problems with my tires but I don't have very many miles on them yet.
What is the date on your tires? The date can be found stamped on the side of the tire after the DOT "nn" "nn". The first "nn" is the week of the year and the second "nn" is the year.

Hi Tom, the DOT # is 3010 on all tires.

Mine has all letters after the word "DOT"  ....   This is strange.... back tires have letters after the
DOT, and the front have week+year as U have indicated..

Many times tread separation and then failure is caused by not keeping the pressure in the tires inflated to the correct amount.
Were the tires checked regularly? I've had tires go flat on the inner dual and never noticed until I did my pressure test before a trip.

I agree that under-inflation will cause a blowout.  Unfortunately it is a science project to determine what the right pressure should be.

Our 2007 chassis has the original tires and I have no plan to change them anytime soon.  I got 12 years from the last set with our first motor home.  With our PC, the tires are designed to handle a lot more weight than actual weight so I think we are okay as long as the right PSI is in them.

Oh, our rig is stored indoors all the time as well, no sun, no cold, no dampness, etc. which helps a lot.  17,000 miles on them so far.  They still look and smell like new.

If one of your duallies goes flat on you, better quick put 80psi in the other.  It's always a good idea to carry a cheap 12V tire pump.  I carry a repair kit like this one, bought cheap at Walmart.  It looks big bit it is very compact.  If the tire has gone flat because of a nail, I hope to fix the flat with a plug (not the Slime) while still on the rig.  It's much easier than changing the tire.  Then casually make our way to a tire repair shop for a better patch-from-behind repair.

Driving on one good dual and one flat, is a sure fire way to insure the good tire blowing out, from being grossly overloaded, even for a short duration. 

Ask me, how I know that?

When the second tire blew from being overloaded for less than ten miles, the dual replaced and a couple hundred miles later it caused more damage than a set of 6 would have cost new, way false economy.

Word to the wise, don't try to limp in or to somewhere else, STOP and change the bad tire.  I never went anywhere after that without road service.

Did anyone ever try thos 12 pumps to actually pump to 80lbs?  I tried doing that with what was a high end 12 pump, and it blew up before I got to 70lbs. (Was rated at 100+lbs)

Bad set of tires, under inflated???  It would seem that if there was a problem with Michelin tire we would see more comments about them. I have the same tire on my PC,, also had the same tire on another RV. I check my tires all the time. Scares me to death thinking about a blow out driving these beast.  Flat tire I can handle. blow outs   scary!!!!!!

this is the inflator I use, no problem going to  80lbs..

Ron,  I have fixed numerous flat with a kit. (not on the RV yet,knock on wood, other cars)  Got in trouble at Discount tires..  they told me they use some other plug than the tar ones. I also carry a kit.  Have you heard anything like that.  I guess when you plug into the steel belt it obviously tears some of it.  But how else can you fix a nail flat????   They fix flats also. I asked at couple of auto parts store,,nothing yet. Need to do some more research..

 BTW, like I said in earlier post.  You need to know how to change a tire,, sometimes you can not get Roadside Assitance.  I have RA, could not get anyone on the phone, no cell service..

Many thanks for the comments.
Specifically, the right side inner rear tire went first. I limped into Fredericksburg at 25 mph and had the spare tire installed. The inside left side inner tire went some 10 miles from home, so I limped in straight to A & A Tires in Kerrville. They made me call Michelin Consumer Care and told me what information to give. Michelin then called back to A & A Tire and made a deal where I got about 50% off 2 new tires. Michelin would not discuss the other five tires that were the OEM from Ford/PC. Guess I'll wait for them to come apart - at least they are all rear tires!
