Tread Separation on Maxxis M8008

Tread separations don't just happen overnight. They are most often caused by some form of tire damage - inflicted or built-in - that will eventually cause the tire to fail completely.....

I'm going to disagree with that.

While in service damage to a tire can cause a "belt leaving belt separation" (what is commonly called a "tread separation"), the most common cause is a deficiency in design - meaning the type and placement of materials in a tire (per the specification) and the material specifications. Manufacturing issues (commonly called defects) are hardly ever the cause.

I'm going to disagree with that as well.

If there is in service tire damage or an actual defect, then, yes, a tire expert would be able to pinpoint the cause. But because most tire failures (and I'm excluding road hazard related "failures" here) are design deficiencies, there is an absence of evidence and therefore any "cause" is speculation about the design.

And lastly, tire experts of the caliber to be able to examine a tire failure and at least have something intelligent to say about it, do NOT reside at tire dealerships.

But tire manufacturers have such experts and returning a failed tire to them is a good idea. But do NOT expect any honest assessment in response to you, the consumer. There are legal liabilities in play and anything written down can be used in a court of law. Any expert who can do such an examination would be aware of those legal liabilities and would be very careful about what he said.
