I guess the only way to tell is to take it to a track and see how it works as on street should be no problem.
Thanks for the info, but my car will never be tracked due to where I am.
I see many people in the forum have 285 at the rear, so meaning most of them have off ratios, I wonder if they run into any issues other then potentially scrubbing the inside corners.

Overall pretty happy with the grip. Recommended to anyone looking at a better match for our c63s.
What you using for the front wheels with those 295/30 rears?

YICS NZ, how are your 295's holding up?

How are they wearing?

What tyre Pressure are you running?

Can you give us all an update please.

Thanks SBH, not sure why Mercedes didn't put a larger setup on the rear.

Parked next to an F80 M3 at the tyre shop, even it had wider tyres then our factory ones.

I will get a 10.5" wheel once I find something but this setup is fine for now and looks insane from behind.

I love these factory cross-spokes so hope I can source them in the 19x10.5".

If anyone can help out it would be much appreciated.

great news ! but I'm really hesitant to go for 295s in the back as I have the stock forged cross spoke 19'' wheels.

a 295/30/19 should have a 10.5 in wide rim and no smaller than 10. It is actually 1.1% smaller in diameter so no problem there but you should get a 10.5 inch rim and maybe a off set change.
The fronts should go no larger than a 255/35 19 on the stock 8.5 inch rim as the 265 should have a 9.5 inch rim and no smaller than 9
245/35/19=807 revs per mile--dia=25.8
265/35/19=790--dia=26.3
285/35/19=774--dia=26.9
295/30/19=799--dia=26.0
looks like the OEM wheels/tires don't match as it is. So going 255/35F 295/30R is a step in the right direction!

Outside diameter is only one aspect and arguably not the most important one. Of course the speedo is set to the 26.3 in diameter and other sizes will not show correctly.
The width is more important as having a narrow rim and large tire pulls the tire in too far at the bead and the tread is not flat on road. And going to a 30 aspect ratio is a harder ride. Go to the tire rack charts and they will show you the best rims width for any tire you want--they show the acceptable range and preferred width.

So 295/30 fits our car, but it bulges out with our stock 9.5, not the most ideal visually. I asked around some big name wheel companies, none recommended this set up. I am puzzled

yes 295/30 does bulge but only so slightly that most couldnt tell at all. I prefer the tiny little bulge which can actually protect the wheels.
the grip from 295 is so much better than the 265. Im sure You wont care about the little bulge

I couldnt tell if the ride is harder at 44psi. For the factory 265 michellins i cud only handle 38psi.
having 295 certainly does not change the handling at all.

too happy to not have time coming back to mbworld

running 42 in the front and 44psi on the rears, used to have 36 front and 38 rear but the handling went too bumpy so had to pump them up. Now the car handles the same as when I had factory michelins in their 38psi.

Wearing seems to be quite even. I drive fairly hard on normal roads anyway plus a few trips a week to my golf club via hilly windy roads so the tyres get quite a bit beat on them.

to anyone whos concerned about 295 at the back they should really go for the 265/285 setup. The increase in grip is worth of any doubts.

If it is a sedan you are talking about --you know the proper pressure is 38 front and 33 rear with the stock tires. Don't use the numbers on the door post as they are not correct and only for EPA. The correct ones are of course on the back of the fuel door.

im running 255/295 but even on factory 245/265 the recommended rears on 33psi is simply too soft for me. I prefer a loose rear

YICS NZ, I followed your lead on this one.

I've been running factory pressures up until yesterday.

I drove down to the Gold Coast yesterday changed to your recommended pressures and it's a totally different ride now.

Driving round the coast and the trip home on the highway the C63S felt light and agile, brought an unexpected smile to my face.

Factory pressures was way to soft even in Sports +.
