Safe to use wheels that are drilled for a 14mm bolt on a 12mm bolt vehicle W203?
TIA.
I once tried to apply 12x1.5 lugbolts with a 55 degree head angle to wheels with a 12mm bolt hole and a 60 degree bolt seat. That small difference caused vibration. Once fitted with 60 degree head lugbolts, the vibration went away.
I doubt your wheels will fall off, but the vibration may not be tolerable.

It looks like for ball seating, they make a R12 and R14 (sounds like freon). I am assuming that is the seating between a 12mm or 14mm bolt with ball seats?
I forget to mention that my wheels have taper/conical seats. Does the seat matter in my situation for a wheel that now has to use 12mm conical/taper bolts and wheels are drilled for 14mm concical/taper seats?
Can anyone confirm? Luke?
I should have made myself clear on the first post that my wheels and lugs are cone/conical/taper. It appears what Luke and Bumpnzx3 were referring to were ball seats.
Sorry for the confusion and I hope this thread helps others.

A 16" OEM W203 wheel originally 12mm , I'd like to drill them to fit the 14mm W204 bolts. Can I than use the OEM 14mm bolts from the W204 and fit them to a 2009 C300 for winter?

I will test for brake clearance first without bolting the wheel up. If that works out I'll take it to a machine shop with one 14mm bolt and see if they can do it right. Otherwise I'll need wheels.
Do you have a wheel I can use for winter that's less expensive than the OEM Mercedes offerings for a C300 Sport that's decent looking and priced right?


Thanks
