I bought new tires two years ago and have roughly 10,000 miles on them.
They are dated at 2012.
I pay close attention to the air pressure and run 80 PSI in them.
On the way home from Patterson the drivers side rear tire became oval.
I believe the belt is coming apart.
I got a new one coming from tire discount direct.
My concern is that the other 5 may be a problem as time rolls on.
I am wondering if anyone else out there has experienced this problem.
I am running BFGOODRICH T/A commercial 225/75-16
They now carry a commercial T/A 2, which makes me concerned that there was a problem with the T/A 1 (now discontinued)
We called BFGoodrich and also Tire Discount Direct.
Never got any "real" answers from either.
So I am asking my fellow GMC'ers
Has this happened to you?
I hate to buy a new set of 6 when they are less than 3 years old, with ALOT of tread still left on them.
No one can guess the future, just curious if this is a strange, or fairly common issue.
Needless to say, I will be paying close attention to my tires, from here on out.
Thanks for being there.
Sincerely,
Glenn Gardner

Glenn,

Don't use BFGs but I think 80#s maybe a little over inflated.
I personally do 65# all around, some do a combination.

just my 2 cents.

80 psi is not "technically" overinflated. But it is the max inflation pressure for a Load Range E tire.

If you look at the tire pressure chart, and reference the GVW info in your Operating Manual, you will see that no tire on your year model GMC ever needs more than 65 psi unless you have overloaded one or more axles. That extra pressure MAY have contributed to your tire problem, and definitely lowers the amount of traction you have (a safety concern).

http://gmcmotorhome.info/tires.html#PSI

Overinflating MIGHT get you a little better gas mileage, but anything more than what the chart says is not a good idea. Pay particular attention to the first sentence of the fourth paragraph in the "Tire Safety Seminar Summary" section of the following tech article:

I have used those tires for many years. There is nothing wrong with the TA1. The TA2 is just a slightly different thread design.

I change them out every 6 years.

You are running way too high a pressure. I use 65 psi all around and you could even use less. Since I drive the speed limit on interstates I prefer the 65 psi.

I recently had premature wear on BF Goodrich tires -- but not on the GMC. I called 866-866-6605 to initiate a claim -- they use your phone number to track the claim -- and then I went to the dealer. BF Goodrich allowed a pro rata settlement.
I was very happy with how they handled the problem.

Thank you all, for your feedback.
I will drop the tire pressure down to 65psi.
And...will hope the other 5 stay round ! :0)
P.S. Emory,
Hope you are feeling better during your recovery.
Missed you at the GMCMI rally.

Glenn - Several years ago I put new BFGoodrich All Terrain T/A's on my 1-ton truck. With less than 10,000 miles on them we headed from Seattle to Albuquerque with a 10' Arctic Fox Camper on the back.

Just outside of Gallup the right rear tire blew. The bead had disintegrated. The highway patrolman who stopped to help us said he had never seen that sort of failure. Most of the bead just wasn't there anymore. We put on the spare and bought a new tire in Gallup. After that I checked the beads of the remaining 3 tires at every stop.

On the way home in Northern California the left rear bead started to go. I put on the spare and we drove straight home.

BFGoodrich replace the 3 remaining tires and the 4th one we had replaced in Gallup with new tires at no charge. Once off the rim it was obvious that all the beads (except the Gallup tire) were literally falling apart. They never admitted to any problem or any wrongdoing. Seemed a bit odd that they would so readily provide new tires.

Good time to start a two every two rotation.

Buy two tires. One to replace the bad one and one other. Put these on the front. Put the left over good tire on the spare.

In two years buy two more and put these new ones on the front, moving the two year old tires on the far rear. Keep the best of all used tires as the spare. Store the others.

Two years from then pick up two more new tires. Again put these on the front, move the fronts to the far rear and the rear most to the mid wheel position. Keep the best used tire for the spare. You should have four old but still usable tires to sell on Craigslist. They will work just fine on a pick-up.

Continue to buy two every two years. Every other time you'll be able to sell a set of four to recoup some of the expense.

In April 2017 and again in April 2018 I had the same brand and size of B F Goodrich tires blow out in the left rear of my GMC. Each time it caused $2000 worth of damage. Tires were purchased in 2011 and had about 22,000 mi on them when they blew.
On inspection by retail installer, all the remaining tires have had the bead sliding out of the American Eagle aluminum wheels by a about a quarter of an inch. B F Goodrich customer support will do nothing about this, because the tires are beyond their 6 year warranty period.
It looks like the cord that goes through the bead must be failing. This is allowing the bead to lift out of the rim and eventually fail, blowing out the tire.
I had never heard of this happening before, but this is an alert to all to inspect the beads on their tires for potential failure.
I can post pictures if anyone does not understand what to look for.
I am in the process of deciding on replacement tires.
?Time for another discussion of the favorites out there among the group.

Mine are all dated 2414. I lost one in San Antonio on the way to Tucson.
It was my fault because I heard "something funny" and didn't identify it
before it blew -- fortunately at low speed, causing minimal damage.
They'll ALL be replaced before 2419!

Glenn,

Sorry to say that if you bought tires two years ago that were dated 2012, they were already 4 yrs old when you installed them. You should probably not run tires that are more than 6 yrs old, so the tires that you have on your coach are probably timed out. When you buy tires, look at the date codes and do not allow install of tires that are more than 5- 6 mo. old, no matter what kind of price break you get. Our coaches are especially hard on on tires, especially in the rear where the sidewalls get strained every time we turn a corner, so 6 yr old tires is the max you should be running. Now Michelin Tire claims you can go 10 yrs, and some have gotten away with that, and some have had blowouts at 6 yrs.

As a side opinion, the installer should have never sold you 4 yr old tires. Personally, I'd run them over the coals on that and insist that they compensate you in some way for this issue. JMHO

Sorry you are having this problem.

OH....just noticed that you posted this in 2015, so your tires were one year old when you installed. Sorry...spoke to soon Smile

Discouraging as BFG are Michelin. I had great luck with my LTX. Sounds like a bad batch run. What is the country of origin just to keep score. So far good luck w Cooper HT3. And much less money.

Tires too old that should have never have been mounted.

If you think the GMC rides like a truck, it''s because of that 80 psi --
that's MAX, not recommended running pressure. Every manufacturer publishes
a chart of recommended pressure vs weight. Get the coach weighed, "axle"
by "axle" and use the recommended pressure. You'll enjoy the ride a lot
more and the tires will probably last longer.

Scooby Doo —

Why are you running 80 psi?
That might be contributing to the wear problem you are stating. You are probably reading the sidewall that say Max Tire Pressure is 80 psi. That doesn’t mean that you should use the Max pressure.
You should base your tire pressure on the weight on the tire. Most GMC motorhomes do not exceed 2000 pounds per tire.

You are running way too high a pressure. I use 65 psi all around and you could even use less. Several GMCers run even lower pressures. Since I drive the speed limit on interstates I prefer the 65 psi.

There is nothing wrong with the TA1. The TA2 is just a slightly different thread design. I have used both over several years and don’t notice any difference.

The last time I bought tires from Discount Tire they put on 4 T/A2 and 2 T/A1.
Since I always inspect my tires before I leave a dealer I brought this to their attention and I pointed out that the T/A1 were already two years old so I told them to take them off and replace them with T/A2 tires.

They did so.

The pressure of 80 psi will support 2650 pounds. I checked with BF Goodrich for you and they tell me that the recommended pressure for 2000 pounds is 60 psi.

I was talking to a fellow the other day about the BFG Commercial TA that
threw it's tread. He said that he'd had trouble with them as well and that
there'd been a recall but nobody knew about it. He said his insurance
company readily paid for the tire and damage and told him that they'd get
their money back from BG Goodrich with no problem at all as it wasn't the
first time.
Just what I heard. I had no damage from the 6 year old tire so chalked it
up to luck since I shouldn't have been running it in the first place. I
made it another 2000 miles on the rears but will change them out before the
next trip.

I heard good things about the Toyo HT so am thinking I'll try them next
