Is a Overloaded Tire Damaged?

Tires are rated to carry a specified load at a specified speed at a specified pressure. Operate to far over any rating has the possibility of damage. From my experience, improper pressure and speed are the more common causes of failure, along with impact and puncture.

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.

"Overloaded enough to cause the prior tire to blowout."

Sounds like you have discovered you are overloaded and are concerned replacement tire has been damaged after traveling 650 miles while still overloaded....

Tire has been damaged....question is/are
How much 'overloaded'...tire pressure......speed during the 650 miles/continuos miles or cumulative miles

define overloaded.. 1% 5% 25%?
At 1% it will likely die of old age before it fail of overloading damage. At 25% I would be replacing it - overloading causes excess heat, which causes internal damage - not all of which is visible.

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.

Need more details! Tire type and more about the overload condition.

Does prior tire mean the one paired on the same side? Any time a tire fails on one axle, the other tire on that side becomes extremely overloaded, and should also be replaced.

The higher weight ratings of special trailer tires leaves them with no reserve capacity. LT tires are a much tuffer animal and will fair better under such conditions.

If it was slightly overloaded I don't think it would be damaged unless the air pressure was low and it got hot or you hit a curb or some other object.

If it was severely overloaded I believe the internal components of the tire can be damaged at highway speeds.
