Glass and radial tire wires can hide in the tire.
Turn the tire inside out and look again.
I just discovered the wonders of radial tire wires. Could not find a problem with the tire, which is a Gator Skin and thought I might have a burr in the rim. I had a bunch flats over a short period of time. I took it to a shop to look at the rim and the mechanic found a wire in the tire I had not found.
