W220 S500 AMG Alloys BOLT SIZE?

[MRN1K]

Hi All. Hope you are well.

Can anyone help me identify what bolt size I need for my W220 '53reg' S500 with the factory 5spoke AMG Alloys. It has a factory AMG kit and wheels.

Many thanks

Nik

I have. Even the tyre place measured them but a couple different sizes. So just needed to know the correct size.

MB parts dept ? They would supply the correct ones

There aren’t a “couple different sizes” on your car. The hub will only take one size.

Could be that you have some spare wheel bolts in there (usually shorter and steel specific - if you have a steel spare), Go to MB and get the right ones with your vin. about 3 pounds each

Change them they look rusty, but I am OCD

Thanks All. Yep the plan is to change them all. MB parts were not very helpful locally so going to try another dealership!
Wheels just had a full refurb so want to change all the bolts anyway so they look good!

M14 x 45mm shaft with R14 head.

Pull out a bolt and measure the length of the bottom of the radius to end of the thread. Should be about 45mm.

Good stuff, I did think your alloys looked mint

I replaced all mine on the W251 last month as they were showing rust, as I said OCD, whilst you are at it, consider getting rid of the locking nut, just a PITA to be fair, there will come a time it breaks or you lose the key
