Ever had a bead fail while mounting?

I just did.

Went to Pep Boys today to pick up some tires for my daily. Cornell P1000 or something like that. Cheaper radials for the winter. I mount the first one with no issues, practically fell onto the rim. The second one, however, decided to fail. I got half the tire on, then as it was coming around to knock the rest on, the bead busted. I stopped there.

I dismounted the tire and went straight back to Pep Boys. I wasn't able to reach a manager, but I did get ahold of, well call him Jasper, who sports a weight belt and was lifting boxes when his employee interupted him. He eyeballs the tire and tells me that it takes over 40,000 psi of presure to break a bead, obviously I must've mounted the tire wrong.

Now I'm not a newbie, I've mounted over 500 tires I'd say and never had one fail like this. It didn't even struggle, just broke. Hell, I've even had tires struggle on the machine and not fail. The machine in question is an Accuturn 2120, not nerely enough *** to break a steel bead without a defect. If the tire struggles the least bit, the machine just stops and you regroup. No way it could've broken this bead unless it was defective.

I explain to Jasper that this is not my first time mounting a tire and I'm not exactly trying to mount tires on the side of the road with 2 steak knives, this is a "professional" tire machine. He tells me that he used to be a manager and thats what the manager is going to tell me. They will warrantee for a manucfacturer defect but not for someone trying to mount the tire improperly.

The manager will be in tomorrow at which point I will continue this saga. I'm just venting seeing as most likely I will have to eat the cost of this tire and buy another one.

 

I had to read this a couple of times to be sure I understood what broke.
I've mounted hundreds of tires as well. Never had one break this way but it will be interesting to see what others have to say.
Surely this won't be a problem. Good luck.

 

The bead, the very inside of the tire. Ya know what F it, its in my trunk, I'll snap a pic.

 

So did the bead tare?

I've mounted some really old rotten tires before and had this happen but there is no excuse for a new one to do it.

 

I saw a guy break a bead by using too much air to seat the bead.He said it was at 80 PSI when it blew. Our machine says 40 PSI maximum when trying to seat the bead.If it won,t seat it gets broken down and moved on the rim.

 

Sorry dude.. I didn't mean that I didn't understand YOU.. I didn't believe my eyes.. a new tire with a blown bead upon mounting? Wow.

 

Yes.

Didn't even get that far.

Yes.


So good, I'm not crazy.

 

dam i would have to say it was a defective bead..like the dude said to you ..it takes over 40K psi to break a bead, well obviously you dont have anything that would be able to apply that much pressure now would you? I think you could use his own words against his argument..and win with out a doubt.

 

Amazing.
Darn good thing it broke then and not on the road!
Make that point and mention that insurance claims could have been a lot more expensive than a replacement tire.

 

Where was the tire made? The Cornell name sounds familiar. I remember a news story recently of tires made in China that the belts failed on because they had left out a layer of rubber between the belts in the manufacturing process. The NHTSA had ordered a recall of them but the importer was resisting because "It would put him out of business and it wasn't his fault". He had to recall them.

I did a search and found this:

It may not be the same problem but it sounds like they have a trouble making a good tire. Take them back and demand a full refund and buy a quality American made tire. You can report this as a defect to the NHTSA

If I get even any hesitation about a refund on a roduct I'm "not satisfied with" I just say; "Either you take it off my Visa card or I will call them and have it taken off and tell the world wide web why."
It works too.

You did charge the tires, right?

 

pep boys blows. thier fault or whoever's` they still blow.

 

A guy I worked with at the resto shop where I used to work had a couple of beads like that fail when being mounted, but they failed when the tire was being inflated to seat the beads. Sounded like a shotgun x10 and knocked the guy flat on his ***. Scary, we thought our air compressor tank exploded.

Mental note: Don't ever buy tires from Pep Boys

 

Wow, thank you sooo much. The tire in question was made DOT 5306, so its a little bit after the recall ones, but I'm still going to use that to argue with. I did forget to mention though, They only had 3 tires in stock, so they gave me the display model. I have no way of knowing if this one was the one on display or not, but whos to say that this one wasn't missed in the recall?

Yup and thats my last resort.



BTW anyone remember how to read the DOT #'s on tires? I know the year and thats really all I need to know for recaps at work.

 

You should get a trained professional to mount your tires. It says so right on the side. Thats probably your problem.

 

Most of the dot is plant specific, all I can explain are the last 4 numbers which are the build date , say 2103 for example, the first three are the day of the year and last is the last # of the year. So 210'th day of 83, 93 or 03 etc.

And to answer your question, IMO the tire was junk to begin with or a weak point in that area to be more prone to breakage. I've mounted thousands of tires and havn't seen it too much at all.

 

That can't be right since mine is 5306, there isn't a 530th day in the year!

 

Oh ya, **** OOF!

 

****, I messed that up. I mean't at least what i've read the first two are supposed to be the week made and last two the year. But that doesn't make sense either . No 53rd week LOL. Unless we're going back to the Pagan days anyway. Maybe an extra week of work huh?

 

Thats what I remembered as well, but I thought I must've been wrong, or the stamping is wrong.

 

Al I can say is CHEETAH

Here is how to read the DOT info off the NHTSA website:

Tire Labeling - P***enger Vehicles

P***enger Vehicle - Sidewall Inner Circle


U.S. DOT Tire Identification Number
This begins with the letters "DOT" and indicates that the tire meets all federal standards. The next two numbers or letters are the plant code where it was manufactured, and the last four numbers represent the week and year the tire was built. For example, the numbers 3197 means the 31st week of 1997.

The other numbers are marketing codes used at the manufacturer's discretion. This information is used to contact consumers if a tire defect requires a recall.

Tire Ply Composition and Materials Used
The number of plies indicates the number of layers of rubber-coated fabric in the tire. In general, the greater the number of plies, the more weight a tire can support. Tire manufacturers also must indicate the materials in the tire, which include steel, nylon, polyester, and others.

Maximum Load Rating
This number indicates the maximum load in kilograms and pounds that can be carried by the tire.

Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure that should ever be put in the tire under normal driving conditions

 

damn, i've seen that before, hundreds of tires a day go thru my shop, and this happens here and there on cheapo tires, ie. cornell. return all of them and buy a quality tire.

 

Thank you once more. Mine is 5306, so somehting somewhere aong the line is wrong.

 

Must be the Chinese calender!

 

Since you are looking at this thread....did you get it straightened out?

 

Went back to Pep boys today and Jasper informed me that there werent any managers there after he told me last night one would be there until 6. *******, I was there at 5.

Drove up the highway a few miles to the next one. Replaced the tire without any question. This one is really brand new 4307.

I now plan to call the store hotline and let them know how unhelpful Jasper was. Now wonder the ****canned him from being a manager.

 

You have issues.

 

I'm glad they changed the tire for you.
I guess you won't be sending people to Jasper anytime soon unless it's to aggravate him.
