I have a set of zender sport wheels. Not my pic but these ones - https://pp.userapi.com/c836634/v8366..._KKxlSw_jg.jpg

I'm having trouble confirming which lug nuts would be correct. I think they are ball seat but Im not certain, and I also know that ball seat lug nuts are available in different radius size.

Can anyone confirm the correct lug nut style for this wheel? Ive been searching but coming up with nothing.
