I just bought 15 mm spacers, but have no idea what size lug bolts to get. Any idea?

add 15 mm to your bolt lenth you have now. you should get 6-7 good turns into the thread for saftey

Your stock lug bolts will work fine.

the factory lugs are (M12x1.5mm). they are 61mm in length. just like jnolte said, add 15mm to this then that is the size you need. any spacer wider than 5mm, it is recommended that you buy longer wheel lugs!

better safe than sorry!...you wouldn't want a wheel falling off while driving, now would you?

You will need an inch and half of threading. My aftermarket wheels with 15mm spacers have this exact length so the OEM bolts worked great!

I tried to use my factory lug studs with the 15mm spacer and they weren't long enough. I wonder if the dealer will have longer ones?

like i said, they weren't goin to work. that is too big of a spacer too run stock lugs "safely". and no the dealer doesn't have longer ones. you have to buy them aftermarket!

lol, we already told you!

Go to a local wheel shop they should be able to help you. Make sure you get whatever seat the wheel is "ball seat" or "conical Seat" MB wheels are usually ball seat

jnolte's initial advice and subsequent comments are very sound. If you have to ask the question, you should go to a reputable wheel shop.
