[quote name="Bulti" post="170309" timestamp="1445528probablyily, no. I've had a flat in the past before, but no damage like this. Maybe the tear indeed came from driving with the tire being completely flat. The deflation was in any case very suddenly.
The tires are Goodyears. I think any tire would have thrown in the towel in this case.[/quote]
The damaged tire is known within the industry as a "run flat". The majority of the damage to the sidewall happened after the penetration during rollout. If you were traveling at 60 mph you probably went 200 to 250 feet before you came to a complete stop. In that distance the tire rotated 30 to 40 times totally without air pressure and around 25% of the weight of the vehicle on it. Thus the sidewall damage. You can find examples of this kind of damage in most tire dealers scrap pile including Michelin. Not that uncommon.
