W163 wheel bolts

[Huw 800S]

Hi,
I have just bought a genuine set of 18" AMG alloys to replace the 22" aftermarket wheels on my W163 ML55,
My confusion is, do I need tapered or radius bolts? Both seem listed on that auction site.
If anyone has a genuine set with locking bolts and tool, that would be great

You need 14mm radius head bolts on your ML55.
Just double check the ones on eBay are the correct length and diameter (M14 x1.5, 17mm head and 27mm long
