C63 W205 - Moving from 18 inch to 19 inch wheels ... how hard is it likely to be?

Apologies if this has been covered before but I couldn't see any specific posts...

I quite fancy moving to 19 inch wheels for my 2016 C63, it currently has 18's with 255/40 & 285/35 tyres.
If I move to 19's can I just keep the same tyre profiles or do I need to get lower profiles to keep the same overall diameter and avoid rubbing on the wheel arches etc?

Looking at buying new wheels seems to be crazy complicated .... width, pcd, rolling radius and offset!!! Does anyone know the specs of the OEM 18's?

Would it be better to check the classifieds and buy second hand 19's off a C63s or similar? I assume 19's were a purchase option so maybe 19's will not have a fit problem?

Cheers
 
I had 19s on my C63 and have 19s on my E400 Cab. Haven't found either too hard unless the road surface has ben horrible (1 mountain pass in Switzerland was cobbled, that wasn't much fun)

Look inside your fuel filler cap. Should tell you in there the tyre option sizes for your car. Should let you know what tyres are required for the 19's
 
Buying the factory supplied 19 inch wheels from another C 63 will help you to make sure that the wheels and tyres are the right size, and probably the easiest thing to do if you’re unsure.

Had a look but it only gives you recommended pressures for the different wheel sizes. I might try the local dealer and see if they have an idea on the OEM spec for 19's.

I managed to find this online which matches up with the current OEM 18's ...so the 19 info should be good.Screenshot 2023-03-21 at 16.21.53.png
 
OEM 19s are
Front 245,35,19
Rear 265,35,19
With my other wheels I have gone up to 275 35,19 rear and are quite comfy at that

Sorry, last post went wrong. Is the car a Saloon, Coupe or Estate?. I have a set of MB factory OEM 19's for a 2017 C63S 205 Coupe, mounted with winters. These are the wheels if you didn't go for the 19/20" option, which I used for summers. The sizes are 255/35 R19 front and 285/30 R19 rear, as I recall (they're all properly stored away so I don't have the wheel part numbers to hand). I actually don't have a use for these as I no longer run the 63S. If you think they could be useful let me know (they've only done around a 1,000 miles so are straight).
 
It's a coupe with 285 not a saloon

I think you may have misunderstood the OP's post . The question is how hard the job/conversion might be to actually do . As opposed to how hard the car will rise afterwards.

OP might explain 'why' 19's are being considered . For looks or performance , both ?
 
The main difference between C43 and non AMG W205 is the front ET. I think C43 is 25 and non AMG is 44. The rear ET is the same for both.
Nothing wrong with the ride on 19” wheels, just leave them 2psi below Merc minimum for 2 passengers +luggage. Much more even wear across the front tyres as well
 
I took it as he wants to put 19" wheels on his C63 which is a straight swop from 18" or am I missing something 🙂
Me too
 
It is mainly for the looks but also the availability of Michelin PS4's which I can't find for the 18's. From the responses here and some internet trawling it looks like a straight swap with a minor drop in tyre profile (which makes sense if the wheel diameter is increasing).

Thanks for all the helpful answers...much appreciated as usual.

It's a coupe, do you have a picture of the wheels?

If you’re going to the trouble of replacing the wheels, then do make sure that they are Pilot Sport 4 S you fit rather than Pilot Sport 4. You wouldn’t be the first to order the 4 instead of 4 S in error, and that single letter makes a world of difference!

They’re currently stored flat, in the dark, in covers. These shots were done before I put them away. They have TPMS on them as I recall.

They look great...did you say they were up for sale?
