Lug bolt size
)- I'm familiar with only 2 lengths for the R.The spare tire takes the shorter length and comes with extra bolts if you have the optional 18" wheels, instead of the 17" wheels (which come standard).
This is because the 18" wheels have longer lug nuts.
On mine I carry around 5 short lugs with my spare when I have the 18" wheels bolted on with the long lug nuts. When I put on the 17" wheels for winter - I don't bother with the extra lug nuts since the existing lug bolts will work on the spare.
If fitting aftermarket wheels, you're on your own and should consult with manufacturer of the wheels, who--if they're reputable--should be prepared to help.
There should be ZERO surprise that "gorilla," "mcgard," etc. don't do Mercedes. They do 'merikun iron.
