Hi All,
Please don't insult me if this question is a stupid one- I've looked through the forums and have found some (confusing, honestly ) threads about replacing wheels, but am not sure how they apply to my case. I'm looking to purchase a pair of OEM wheels off a 2017 c43 amg (the split 5 spoke wheels, not the multispoke wheels), and am wondering if they will fit on a c300 4matic? My vehicle is equipped with the base 17" wheels. The wheels I'm looking at are:
Front: 19x7.5, et 33, tires are 225/40/19
Rear: 19x8.5, et 52, tires are 255/35/19
I guess I'm also wondering if I can reuse the same lug nuts, or of there is aything else I need to get to prepare for the swap.
Thanks for your help!

The factory 17s are 7x17 et48.5. After going to this offset calculator, I see the following changes:
Front: inner clearance will be 9mm more / Outer position extended 21mm
Rear: inner clearance will be 23mm less / Outer position extended 15mm


Now with this updated information... any thoughts regarding whether the wheels will fit?

Yes they will fit and yes you can reuse your lug bolts.

Did you end up getting these rims, if so, did they fit?

I have put C43 wheels on my C300, they stick out a bit because of the offset, giving it an aggressive look. I love it.

Yes, they fit with no issues st all. Incredibly smooth ride on the 19s with a set of the michelin a/s3+

hello, sorry for reviving this old thread but I’m in a similar situation. I have a C300 with the 18inch 5-spoke wheels. Current measurements:
Front: 7.5 x 18 44 offset. Tires: 225 40 18
Rear: 8.5 x 18 49 offset. Tires: 245 35 18

I want to buy the 19 inch multi spoke c43 wheels with the following specs:

Front wheels 7.5 x 19 ET 33. Tires 235/40-ZR19
Rear wheels 8.5 x 19 ET 52. Tires 275/35-ZR19

Will they fit? Thanks
