Installed new 275 tires on the back on black rims
This is a topic that gets talked about frequently. It was time for me to put new tires on my 2016 c63s sedan. The car came with the Dunlop tires from the factory and lasted almost 20000 miles. As a side note for those who have them on your car, make sure you have them checked because my left front had a crack on the inside with the metal showing. The tire was basically starting to separate. Sorry I forgot to take a pic of this.
I was looking to get some more "meat" in the back and hoping for some traction. The car brakes loose way to easily in second gear and I have had the back-end step out a few times at 60- 65 mph in third as well. Wakes you up quickly, scares u for a moment and then puts a smile on your face.
I purchased the new Michelin Pilot 4s tires from Tire Rack. I kept the front tires the same size but went up to 275's in the rear. 275's fit on the 9 1/2 inch rim without any problem. You can take a look at the spec sheet on Tire Rack's website to see that the 9 1/2" rim will accommodate this size.
I have driven the car only for a few days but the traction is without a doubt much better. Some people talk about the balance being off but I don't feel it. I don't plan to visit the track with this vehicle though.
It definitely looks a lot better with the added meat.

Honestly I don't drive the car hard that often nor do I drive it every day. Also the weather hasn't been the greatest since I installed them but from what I have it does seem to hook up better and I'm sure when its warmer out it will only get better . The 35's in a 285 are 0.9" taller so almost an inch and I think it will look more even with the 30's. It presently has a slight raked look and a lot of people think it looks better but I'd like to fit the 30's to see what it looks like .The advantages of a 35 is the less likelihood of wheel damage and the ride is a bit smoother ...not as bouncy

I don't think it would be that great and it may also lower the final ratio . The c63s already has a low gear ratio and I really wish I had like a 3.27 or a 3,55 as I'll never do 180 on any roads around here and I'd rather have the acceleration . With 3.27 or 3.55 or similar this car would run well into the 10's in the 1/4 mile

Hi C3504matic,
I will be changing mine to 255 and 285's, though will stay with the 35 profile.
Please note that the stock tire is 265/35 which is 26.3" outside diameter, while the 285/35 is 26.85" outside diameter and the 285/30 is 25.73" outside diameter.
So, at 60 mph your speedometer will be showing the following: 60.86 mph when fitted with the 285/35, while when fitted with the 285/30 it will be showing 65.32 mph.
Hope that helps in the decision making.
Cheers,
Mark

I went with the Mich PS4S in 255-275/35/19 and I think they have better traction and are quieter and ride better.
I would stay with the 35 aspect as it fills the wheel well better and I think looks better. Also it will ride better.

275/35 (vs 265/35) at 60.63 mph will show as 60 mph. In other words, the taller your tire, the slower your car "thinks" it's going.
End result, your odometer will go up slower. Also, all car manufacturers have "optimistic" speedometers (although the odometer is calibrated properly).
End result is that your odometer mileage will go up slower and your Speedometer will be close to spot on. Both sound like pluses for me!

265/35-19 = 27 lbs
275/35-19 = 27 lbs
285/35-19 = 28 lbs
295/35-19 = 28 lbs
Based on rounding, I'd say the difference between each increase of 10mm width (+ increasing height) is about 0.5 lbs or 1.8%. I'd hardly call that "much heavier".
When your car is pushing 500 lb/ft of Torque, that slight increase in rotating mass isn't going to make a noticeable difference.
On the other hand, your increase in traction will increase very noticeably.

You actually have it backwards in your above post and here as well.

Another tire size calculator we have is our speedometer correction calculator. This is valuable if you plan to or are already running bigger tires then stock, and want to know the speed you are actually traveling compared to you're speedometer reading. A bigger tire has a larger circumference, thus traveling a further distance for each revolution. A speedometer reads the amount of revolutions your tires are making, not how far you are traveling. Therefore you are actually traveling faster then your speedometer says when you have larger tires then stock, and slower then you're speedometer says if you have smaller tires.

I was responding to RebelC63S's comment:
"Yes, 275/35 at 60 will show as 61.49 mph, which is (as you say) negligible", which is stating the opposite.
Just wanted to clarify for everyone.
