Is a Overloaded Tire Damaged?

Is a tire somehow damaged by running overloaded for 650 miles? Overloaded enough to cause the prior tire to blowout.

Damage from overloading is not measurable. And, any damage inflicted is cumulative. The RMA says any tire operated 20% below its recommended pressure is considered to have run in a flat condition and needs to be dismounted from the rim for inspection.
