Those rims are spec'd horribly, even by "stance" standards. Those rears poke way too much. If I had to take a guess though its probably around 15x10 with a 0 offset.

Looks like rota grids
EDIT: no idea offset as I don't know Miata backspacing requirements.
They aren't grids lol. They look like they could be te37v s.
