So got me some s550 oem rims. But my current lug bolts are too short. Does anyone know what size I need?

Or if someone knows the current oem bolt length size?

Thanks

OEM bolts for the A/C207 are typically 27mm long (thread length) only usually need extended lugs if you've gone for spacers? Do you have a part number for the S550 rims?

Interesting. No spacers. And they are stock.

2 part numbers. Front and rear rims.

How did you determine they were too short?
How many turns do they engage?

Well was trying to put them on and they would not thread in. So I took the wheel off and saw how much the bolt was going threw the rim. Barely couple threads were showing. I then slid the bolt threw my original rims and about 1cm stuck threw it.

alright so look like i need 40mm shank. but i dont know what ball seat to get!

R12, R13, or R14! anyone know??

the rims are off of a 2014 S class.

I know the Bolts may well be expensive from buying direct from Mercedes, but wheel bolts are one of those most miss-understood and under rated items on a car. They are actually expensive for a good reason and not just profit taking. (oh ok Mercedes are not cheap, but it's the same is on other manufacturers wheel lugs as well). Having had an issue once when the bolts on my BMW 6 series came loose on a front wheel (even though correctly torqued and checked) the experience taught me a major lesson.

I agree, I took a tumble in my Ferrari 308GTSi back in the day due to bolt issues.

You might try TireRack. Bought a set of wheels from them and they also sent me longer bolts.
They should have the correct bolts for your wheels. Also, one centimeter in not nearly enough thread to hold the wheel. Knowing that I had that little length holding on my wheels would scare the **** out of me.
I cannot remember what the measurement is, but there is a rule of thumb for the amount of thread needed to safely attach a wheel.


Don't forget to tighten your wheels using a torque wrench. I used 94-96 lb.ft.

Yea i figured this out. So you want 17mm sticking out. Thanks for your input!
