I have an opportunity to purchase a set of used C63 5-spoke wheels for winter use, and was wondering if 18x8.5, ET 33 wheels will fit the C450. According to the seller's tire shop contact, they should fit.

I've read the front is a difficult fit on the 450. Given the same 33mm offset as the standard C450 18x7.5" wheels, it would seem that the wheel will extend 1/2" closer to the suspension and 1/2" further out towards the fender opening. For the guys who have been through fitting alternate wheels, is there enough clearance?

My 2016 C450 came with the 18" AMG wheels/all-season tires which I will use during the Winter months.

I'll get you the offsets when I get home from work today.

OK...here's the info on my stock Mercedes 18" AMG (black) wheels that came as original equipment on my 2016 C450...

Front: 7.5", ET33 - part# A205 401 4800

Rear: 8.5", ET49 - part# A205 401 7200

Considering the stock fronts are 18x7.5 with the same 33mm offset, is an 18x8.5 going to fit (1/2 wider each way from center line)?

It's too close to call. There's only about a pinky width between the stock 450 wheel and the suspension side. It may require a spacer and then it may stick out too far for your liking. I would say someone has to fit one up to know for sure.

8.5J x 19 will fit with ET31, but there will be only a few mm's between tire and suspension, and the wheel is flat with the outside fender. It's a really close call.

See here 8,5j in front.
