The S500 rims are designed for 14mm (diameter) lug bolts and your W210 uses 12mm diameter lug bolts, so you need special "adapter" lug bolts, i.e. 12 mm diam but with larger ball seat than you now have.
The wheels you've purchased are likely 7.5J and ET 46 (is cast in) if they are genuine Mercedes and really wheels for the S-class, and the 17-in wheels Mercedes made for your W210 are usually 7.5J and ET 37, so you could have an offset issue.
Looking at the wheel catalog your pictured wheels look more like the "Rucha" wheel for the W211 than anything in the catalog for W220 (S-class).
Recommended 17-in tire size for W210 is 235/45-17
More info if you can read the part numbers cast into the wheel.
