Moving down to 18s on W205 C63 Wagon

[Amgeeeez]

Hi all

Does anyone know if 18s would fit to my 205 c63 wagon currently on stock 19s?

Looking for more rubber for the look (like an M3T wheel and rubber ratio) and maybe some comfort and noise reduction also.

Thanks

Yes, 18" alloys will fit.

Thank you

Alternatively could I fit slightly thicker rubber e.g.

Currently has 265/35/19 on the rear, could I fit 265/40/19 tyres on - is there enough clearance?

Same for the front increase 5mm tyre wall.

Any help appreciated

Nope....its 13mm more side wall....so over and inch more diameter.... which is significant.
