I didn't know anyone made steel cord tires for aircraft, at least not
for aircraft that I'm likely to fly. All the tires I've seen are nylon
bias-ply tires. The only steel is the tire bead.

Could the steel cord be foreign object damage? In that case, lucky you
picked it up in the tire and not in the prop.

Not sure. I don't know that much about aircraft tires. That's why I posted
here. The material was very fine bristly stiff wire. I just assumed it was
steel cord, since it felt like the steel cord from automotive tires. What was
weird is that it was about mid point on the side wall. The A&P that replaced
the tire was surprised as well. The clubs A & P is looking into it. To try and
figure out if was tire defect or if somewhere something got picked up. It was
very odd.
