Post C Class with aftermarket rims
with 225/45/18 tires?
How are you liking it and if you have any issues with it? I just got some winters with this configuration I believe.
So far so good but just a bit concerned if offset will be a problem.
My summers are the AMG offset 18s with ET 44 (front) and ET 49 (back).
225/45/18 front and 245/40/18 back tire size.

I'm currently in the process of setting up a second set of wheels with 19" aftermarket rims and tyres that would be able to be rotated back to front etc. I've run into a small issue with the tyre rib on the side wall of the new 235/40-R19 front tyres rubbing very slightly on the strut (vertical suspension arm). I've got 10 mm hub spacers on the way to solve the problem, but I'm not sure if that'll cause a new issue with clearance between the tyre and the fender. More description given with photos below.

New 19" wheel fitted on front; Note that the tyre rib on the side wall for curb protection, rubs slightly on suspension strut; Plan on using a 10 mm hub spacer to correct this; Rim: 19" J8.5 ET33; 5 x 112 bolt hole; 66.56 mm bore; Tyre: 235/40-R19 Bridgestone Blizzak
New 19 " wheel fitted on front; Rim: 19" J8.5 ET33; 5 x 112 bolt hole; 66.56 mm bore; Tyre: 235/40-R19 Bridgestone Blizzak Hoping that if a 10 mm hub spacer is added, it won't cause a new issue with clearance between the tyre and the fender.
