C63s on toyo T1 sport 255 35 R19 and 295 30 R19



just got my c63s sedan on a set of new rubber. Thought the 295 30 would be quite aggressive but it fitted ok. No rubbing noticed so far after a day of driving and yet to find out how much grip/how confident that i can accelerate (factory michellin 265 is certainly way too narrow for the power of the c63s).

You have any shots of the car at regular angles? Wondering how much tire bulge there with a 295 rear..

Its surprisingly minimal. Couldnt find the thread width of the toyo 295s but it looks not bad at all.

Doesn't look anywhere close to being at the limit.

Thanks for guinea pigging! Guess I know what sizes I'm going to next!

Great choice, I opted for the 285/35 michelin's instead. Looks phat and certainly helps get the power down!

If I remember looking a the tire rack chart a 285 is the biggest recommended on a 91/2 rim.

Yep wasnt sure if its too big for the rears but the end result is great. Think a wide 285 35 would do the trick too but the front needs to be 265/35 to match the height of the 285.
Overall pretty happy with the grip. Recommended to anyone looking at a better match for our c63s.

Yep its on the limit for the size of the stock multi spoke. 285 would be just perfect but 295 is the widest I'd go on the stock. Bear in mind the thread width might be different too aka a 285 might be just as wide as a 295.

Dont think 255/35 will match the height of 285/35 ie. 255 will be too slow. 265/35 is better

265/35 sidewall will be slightly bigger than the 255/35

if you don't understand that then you need to do some research on how tire sizes work

basically the 255 covers less distance than the 285 per rotation since the radius on the 285 is more than the 255. So when matching the tires the two sets need to be closely matched.

no problem on the sport + suspension mode but got a slight rubbing on the left rear (RHD) when going through a dip at about 90mph in the comfort mode. No rubbing when its in sport+

It is not the correct tire/rim combo even though you can get by with it not rubbing.
the rim pulls the tire in too far and tread is not flat.
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

With that said,
Sedan with stock 5 spoke wheels, the widest tire we can go is
255/35 at the front
and to keep the ratio,
the rear can only be 275/35

What if I want to get wider tires on the back, say 285/295 while keeping the stock wheels. What kind of front/rear combo works?

Thanks

Can't do that as like you said (if you have to keep stock wheels) 255 are largest on front so to keep ratio from factory- 275 rear.
If you go to 285 rear your are ok with rim width but ratio is off some and I don't know if that is a big deal. Your speedo will be 2.3% off
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.

I did not think MB put any run flats on the C63 --I have the MPSS and they are not run flats. What do you have and are you sure they are run flats?
