had this happen to me before...talk about a day killer. mine was a bit more identifiable...
Tire came in, so I dropped the wheel off. Thought I would be funny and just walk in and say, "I think there is something wrong with my tire, can you help me?" and then show him this. I was not as funny as I thought...
Anyways, I pulled this out, and it was in there about 1.5 inches.

My worst was a chunk of thin metal with a nail sticking out of it... the metal whipped around in the wheel well slicing up the fender liner and mud flap. The metal departed, leaving just the nail. Thankfully no paint damage. I made it 95 miles on the tire before the nail finally vacated its new home and left me with a flat.
And by 2012 we should have a better way to patch tires or sealing them with some vulcanized rubber or something.
We sent a team to the moon 50 years ago! We can't patch sidewalls on tires? INSANE.
I *JUST* replaced a brand new tire with under 1,000 miles on it on our new CX-7 thanks to a screw too close to the sidewall (still in the tread).
Here is the problem.
A tire generally has two main plies that are the main casing of the tire. These are the only plies on the sidewall of the tire. Some tires only have one, and some truck tires have three. They can be nylon, rayon, and a few other materials.
When those main plies are breached, they lose strength and start to come apart, just as if you ripped a piece of yarn in your favorite Christmas sweater. In the tread part of the tire there are more plies, two of which are woven steel. They can still come apart but they are much stronger and do not flex nearly as much as a sidewall does.
Patching it is not going to stop the sidewall plies from coming apart. This is why a tire sidewall bulges sometimes if you hit a pothole or something. The air is coming through the plies and is only being held in by the outer rubber itself.
There is just way too much liability involved with repairing tires. We don't live in some third world country, just do the right thing even if it costs you an extra few bucks.
