Another Wheel Question

[MIW615]

My W210 has the "diamond cut" 17" x 7.5" wheels with 235/45/ZR17 tyres fitted and I am contemplating fitting AMG 18" x 8" wheels. The offset is the same so I see no reason why they won't fit, however I have several questions that I would like the forum's opinions on...................

1. I intend fitting 235/40/ZR18 tyres, by my calculations this will keep the rolling radius almost the same - is this right?

2. Will these wheels bolt straight on, or will I need spacers / different bolts or can I just use my existing bolts?

3. Will the AMG wheels "clear" the brake calipers?

4. Do I assume that going from "45" to "40" profile will give me a slightly harder ride?

5. Has anyone here fitted 18" wheels to a W210?

Thanks in advance for any advise / suggestions

Yes correct

Bolt length is dependant on the individual wheels

3. Will the AMG wheels "clear" the brake calipers?
Yes

4. Do I assume that going from "45" to "40" profile will give me a slightly harder ride?
yes, but could be better on bends
5. Has anyone here fitted 18" wheels to a W210?
Cant answer that
Thanks in advance for any advise / suggestions

Thanks Malcolm, pretty much as I thought

Anyone else have any opinions?

I may be wrong but weren't OEM 8" wide rims only for the rears on W210?

if the 8's have the same offset as the 7.5's then your inner rim is 1/4" tighter on clearance
