Minor overloading (10 - 30%) is more likely to show up as a long term structural detachment rather than sidewall disintegration and I have never seen melted cord that could not be traced to low inflation based on the sidewall flex location.
Its very interesting that you should mention tire sidewall flex location. I’ve always believed that the ST tires flex location may be situated where it will be beneficial to the scrubbing action of dual - or more - axle dragging during sharp turning actions. Because I’ve never run across a reference describing such actions in the ST tire I’ve always been reluctant to bring it up.
Here is a quote from the Carlisle Tire Company about their ST tires: “Generally, the ST tire also has somewhat stiffer sidewalls, especially in its lower section. This reduces sidewall flexing, helping it to track straighter and diminish the risk of trailer sway. The stiffer sides also lessen the risk of sidewall blowout.”
Can you give us a technical response to that?
