Different Wheel Nuts Needed?

[Pork]

Hi all,

I've just bought some spare AMGs which are the correct B Class fitment. I'm going to give them to my father to try on his B Class and if he likes them, he can have them, but if the ride is too firm, I'm going to keep them as winter wheels for my B200 Turbo (yet to be bought).

The question is, will we need longer bolts to fit them to my fathers car? He currently has 7J x 17, ET49's on, the AMGs are 7J x 18, again ET49s.

Any advice welcome. I * think * they'll be OK on the same bolts, but can anyone confirm?

Thanks
Pork
