E class W210 wheel studs and offset

[hrd2plse]

I have a E220 estate S/hand, but when the car was new the alloys where upgraded from 16" offset 41 to 17" offset 35, now I have aquired a nice set of 18" offset 30, they fit OK no fouling or protruding, The rear studs where OK, but the front studs bottom out before they are tight, as anyone any advice on correct stud size and length, for 18" alloy with offset of 30, or someone fitted 18" alloys on a E220 (W210)

what are the "nice set of 18" offset 30"?

I was told they where "AMG" but I dont think they are, only markings I can find are Made in Germany, JU via 675KG, 0, 1/6, 03/04. they are 5 spoke with very highly polished outer rim, the holes for the studs are 15mm nb and 8mm thick,
The tyres are 235/40 zr 18.

A picture says a 1000 words.

As i recently found out even genuine wheels may need a different set of wheel bolts, if they arent genuine the combinations are even greater , i needed BMW bolts to fit my wheels to my w210
