Those are interesting looking lug nuts. I've never seen them before. I can see how they would be great with a 12-point socket.
I would be hesitant to use them though. The spare tire wrench that comes with the car has a 6-point socket on it. I think that would easily slip or strip out those lug nuts. Additionally, if you ever buy a lug nut socket to protect your wheels, they will also be 6-point. That's just my perspective.

 

I keep the key and a torque bar in her, plus they come right off with a 16mm deep socket 12 point if I do lose the key for it. From what I've found, they look like Motegi lug nuts, which I might have to go to a wheel shop to order those. If not, then I might have to get em custom fab'd at a shop.

 

They're not quite the same as what you have in the picture, but close:

I did see those ones but I'm looking for closed lugs. They salt way too heavily up here for me to trust open lugs not to fuse to the hub

 

I did a quick Google search and I can't find those specific ones at ALL!!! I did manage to find something similar:

These come in 4-packs: 👉 👉 👉 👉 McGard Chrome

These have 3 different color variations (still 6 spline) 👉 YITAMotor

...and these have only 2 color choices 👉 👉 👉 👉 Muteki
