it comes with 235 front and 255 rear? Why dont they put more rubber at the back? like 275 or so... I mean there's lots of hp and trq!! Come on.

Do you think you can fit 245 up front and 265 or 75 at the back on stock rims?

What you guys think?

lexaltezza

I completely agree and have wondered the same thing. I'm sure they have a good reason though.

BoBcanada

I can tell you, if you put a decent size tire on C63 it will outhandle 90% of other AMG cars.... Marketing move i guess.

No doubt it would understeer under such a heavy car on such a tiny 235 up fronts.!!!!

255 f 285 rear would be a killer on this car!

BoBcanada

I wonder would CLK63 BS rims/tires fit C63?

285 at the back and 265 front... I mean if they work for CLK why wouldn't they work for C63? They are 285/30 19inch rear and 265/30 front.

So with those CLK63 can pull 0.99g at the skidpad.

So I'd bet that C63 would be way better handling car with 285 if they fit or at least 275 rear and 255 if they fit or 245 front.

Someone should try to do that... Im getting my car in July and I would love to try wider tires!!!

I wonder is there any disadvantage of wider tires tho?







Imagine the grip on those!

Spartacus700

Maybe the AMG 19"s

On my '04 M3 I got the 19"s and I was able to put slightly bigger tires on them no problem.... 255/275's

The catch is that I don't like the AMG 19"s they have selected for the C63... the 5-Star wheels look MUCH better... they should just make those in the 19" size for goodness sake!!!

AMG/////

One would think you would have to Flare the wheel wells to get anything wider to fit. Kind of like the 500E/E500's of the 1992-1994

MB have always done this. the C55 has 245 rears compared to my M3 which has 265.

I know the M5 comes with 255 front and 285 rear and that certainly helps when comparisons are made to the E63

AsianML

IS-F has the same problem too.

Germancar1

Mercedes have always been relatively under-tired for some reason for years and years. There is probably an "engineering" reason that only a German engineer understands that would explain this. You know that they at least know that better rubber would make the cars sportier/handle better.

My tire set up from AMG was advertised as 265/295 I got 255/285.

I have 030 package with huge rotors. 18' is not an option but it is width that matters especially in the back.

try and get a 18x9.5 in the rear and 18x9 in the front and do 255/285.

Your unfortunately gonna need a wider front rim to fit the 255's that are on my car. 265 non staggered would also be HOTT with 4 rims all 18x9. Many track cars run non staggered. Good luck and do not be afraid to try new set ups. Just go to a tire shop and ask to experiment with OEM take offs form other models , try the E63 wheels. I have a C class rear on my car for the track it is a 17x9 rear that fits a true slick which catapults my car and my 540 hp CLS cannot spin those. The bolts for the E class and CLS class are wider than the C class by 1mm. Otherwise offsets are so close I do not use a spacer wheel fits perfectly

Rafal

Before you do any of that, check the offset on the new C-Class! It is huge and none of the older C-class and E-class wheels will fit, apparently!
All the aftermarket and replica manufacturers are working around the clock, because they did not anticipate it.You cannot INCREASE offset with spacers, unfortunately...

TMC M5

I would speculate that since these cars are made for the autobahn, the wider tires would be at a disadvantage at the higher speeds...stability wise the wider tires are more prone to tracking with road imperfections and are a bit of an aerodynamic hinderance. The wider tires could help with a better launch and aesthetics...but at the expense of the afforementioned.

mrtesting

I fully agree.. and with the amount of hp + torque that this car has, wider tires could also mean worse fuel efficiency.

BoBcanada

Look at m5 it weights about the same, and those "wider tires" 255f 285r doesnt hurt it to go 330km/h. So i doubt that.

CynCarvin32

Small cars with huge tires never track well. Plus steering feel is often better with smaller tires. I say feel not grip.

Now you can likely do a 245 275 maybe even more with the car but its going to be harder to get to 255.

I made a set of 255 285 fit on a W203 but that required some body work to make it not rub. Fender lips totally rolled, fenders pulled out, re shaped and then painted (on the front fenders). That car was used for road racing jokes but boy did it grip well.

245 265 might be the ticket on the C63 since doing 275 increase the stagger and increases understeer.

We need to see what tuners do for off-sets and what kind of space exists in the front fender for larger tires.

CLK BS wheels wont fit at all. Totally different chassis with massively different (fender clearance).

BoBcanada

thats what I was thinking 245 and 265 would probably be the smartest choice with no modification or rubbering for the car.

Rafal

The only problem is that with 245/40:265/35 and 235/40:255/35 the front wheel diameter is 10mm/0.4" bigger than the rear. The correct match would be 235/265 or 225/255 or 245/275.
I am puzzled why MB insists on missmatching the F/R sizes on so many of their cars.

digo63

sorry guys so what is the best/ widest for the Rear rim ? im looking at ADVAN AD08 they only have 265/30/18 and 285/35/18, they dont have 275's . i have the OEM 18' amg 5 star rims and i really hope some pro can clarify this for me.
thanks !

mzporto

EXCELLENT tires! Had them on my M3 and didn't regret a day! I would go for 265/30. bigger tires can cause rubbing and will increase fuel consumption. It "enlarges" turning ratio, too. I believe MB put 255 for that reason. Just a noob opinion...

Even Money

Why not use Advan Sport??

Jae Duk

275 will fit in rear but I've read somewhere that 265 and 245 front is the best set up

Currently I have 275 rear on mine fits fine without any rubbing issue and I still have stock setup on the front, but it looks like I'll be changing the tires in about 1 month and I will try 245 and 265 to see how they fit and drive

451/443=EW

Cost and Sales!
If MB put those tires on every C63
1- the car would cost more
2- The cost of replacing those tires would turn off many purchases
3- Ride quality would suffer, its still a 4 door car that guys put baby seats in.
4- Complaining wifes
5- Not all roads are created equal, we can only dream of freashly payed roads everywhere.

ATT

I just have the 245/40/18 front and 265/35/18 back, the front is a bit taller, with 275/35/18 will be better as long as it does not rub.

maximooz

I'm not a suspension or drivetrain expert, but I think the narrower tires help with the steering response. Perhaps going narrow is what the AMG engineers were trying to accomplish with the personality of our cars? Just my $0.02.

C63newdude

There is no explanation, it is a total failure and will keep being a failure. Every single C63 AMG owner complains about it. This is a good way to really lose customers.

BMW does the job better, they don't play around, they offer rear LSD, stickier tires and more rubber, it is simple, that is why a M-3 will always outhandles the C63 AMG.

I am sure the marketing has a lot to do with it.
