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.

Truck or trailer??
How overloaded, personally I would never run a tire overloaded!! Axles and tires to me are to me NEVER to be exceeded! If the overload is enough to cause a previous tire to blow, I would replace and correct the overload.
