Rear wheel with center bolt, how do I open it?

I finally had time to switch to summer tires, but surprised to see a bolt in the center of the wheel. And I only realised this after I changed the front wheels, which don't have such bolt in the center, only the regular 5.

The biggest hole on my lug wrench is 32, and it doesn't fit. And this doesn't look hexagonal either. Anyone knows how can I open this? What's the tool name, and which size do I need?
