they look like your common standard 14 inch Benz wheel.
I ran a set of those for years.
you need to drill out the lug bolt holes from 12mm to 14 mm ..........I used
a 9/16's drill .
And you need longer front wheel mounting bolts.
and longer rear wheel studs if you want to do it right.
oh................they come in two widths..........
6 and 6 and 1/2 I believe.
Like a sedan will  have the 6 inch wide ones, a station  wagon the 6.5's.
For better handling and sharper turn-in, I ran the 6.5's in the rear, and
the 6 inch wide ones in the front.
a wider rim in the back is worth about 5 % improvement in straight line
tracking , shaper turn-in, and cornering ability and stability.

Compared to stock steel wheels, they also weight less, thus less unsprung
weight, and they're wider than stock steel wheels, and that helps too.
