Can you guys identify which lug nuts I have?

I have a set of those special sockets made to grab and loosen nuts and bolts that are rounded off. The inside of the socket has a series of spirals, and the harder you twist CCW, the tighter the socket grips. Kinda like the way a screw extractor works. Or, here is another thing I have done before, and it works. The lugs look to be a bit tapered. Find a 12 point socket that will fit over the tip of the lug nut and go maybe 1/2 way down the tapered part. Then use a hammer and pound the socket on hard. The socket should stick pretty tightly onto the lug. Then use an impact gun. It usually works. You'll probably sacrifice a socket or two, but if the other option is not getting the lugs off...….
At least your title didn't say, "What kind of nuts do I have?"
