Tire Failure

Nice post and good time for it. I often forget that the inside of a tire deserves inspection as much as the outside.


Be a great sticky if a post was created to show all the problems can have...maybe I will do some research and follow up.

Great reminder!

Have you reported them to the NHTSA https://www-odi.nhtsa.dot.gov/ivoq

Thanks for the info and good pix, mrekim! Very useful.

The pic of the broken/separated belt is a good one. I had never encountered it before last year when my truck tire did this. If this happens it will not ride well at all and you will know something is wrong. I stopped twice before I noticed the crown in the tire tread.

Good thread and pictures! :)

You will probably be interested in this thread by member JBarca that details, with pictures like you did, his experience with somewhat the same tire failure.

The first is what is called a ply separation...at a high stress area(the Crown) that transition area between body plies and belts. Any separation can occur for various reasons...scrub a curb, a improper repairs, over flex form under-inflation, bead damage from R&Rs,impacts breaks but rarely nowadays from Mfg defects.

In modern terms there is no such thing as a slipped belt, which could only have happened before the curing process as it was being loaded into the matrice. Those being the old clamshell molds/matrices for which now everyone is using the segmentated molds.

The second would go down as a tread separation...here the same rules apply with a caveat...this could be all of the above and or a manufacturing or material issue.
