I was leaving the hospital and on the street in front of our parking lot, i saw 2 of these, i picked them up. They were standing nail up. I don't know if they were too tall to damage a tire ( be crushed down before puncturing?). Is this a construction item that fell off a truck? I have never seen them before.
The base is 2x2 inches and might be zinc, the nail is 2 1/2 inches long.
