Lol, looks like my shoe :V

Just looks like rubber peeling off to me. I doubt anything will come from this.

looks like you ran over a wire brush or somethin'

*agrees with Alphonse* looks like strands from a wirebrush .. there are steel cables used in tyres but never seen one do that before, there would be more damage to the rubber of the tyre if a cable had lost a few strands, looks like you've run something over .. my advice .. grab some pliers and ease them out then using some soapy water check if any have pentrated and punctured..

I would try to pull one of these strings out. It´s more likely that they come from a source outsite the tire as from the steelbelt
If you can pull one out wihout to much force and it is not longer than your middelfinger it don´t come from the tire.

try pullign them out and go from there, just done use too much force, its still possible you broke a belt

Take it in to the tire shop. They'll replace it as it's defective for no cost.

That's a strange place for wire from a bad belt to surface. From the angle that the wires have entered the tire I think it's far more likely that you hit something on the road that left those strands stuck in the rubber. In my experience, a separated belt in a tire will show itself on the tread section of the tire rather than the very edge of the tread or sidewall.

Pull them out with some pliers. I doubt that they're stuck in the tire more than an eighth of an inch.
