I was able to buy a set of 4 slightly used Blizzak snow tires (225/45R17 91h) for my 2010 C300 6M Sport that also came with a set of wheels from the original car that the owner said was a C230. The wheels are original MB wheels with Bolt pattern - 5 x 112, Width - 8J, Diameter - 17", Offset - 35. It looks like the bolt pattern is compatible but its clear that my current lug bolts are too short to mount these on my car. Can I get a set of longer W204 lug bolts that will allow me to use both the tires and the wheels on my car? Possible sources?

Thanks,
Gary

 

Both the c230 and c300 use 37mm lug bolts, you don't need longer bolts.

 

Thanks, but there is something different since my C300 bolts do not extend far enough through the C230 wheels to engage the hub.

 

You are correct, my mistake. You should be able to buy longer ball seat bolts from almost any online parts supplier. H&R bolts look just like the factory bolts minus the Star on the face of the bolt. I'm guessing the wheel face thickness is what is different.

 

I think you main concern should be offset. The 17 x 8 et 35 wheels will stick out approx. 17mm over your stock W204 17 x 7.5 et 46 front wheels. In the rear, your 17 x 8's will stick out approx the same as in front...you may be hitting the fenders with this set up.
