AMG C63s Tire Size increase

Has anyone installed a wider tire set on their C63s? It looks like increasing the rears to a 285 and the fronts to 265 might be tight, but it sure could use a little more rubber on the road!

I know some guys on here have run 275/255 with no issues.

255 f/275 r is ok but
with stock wheels that is about the limit.
With wider wheels and the correct offset you can go bigger with out clearance problems. Saw King Monkey had 305 r

Wow, that's a solid fitment.

I'm hoping to fit 305s on the coupe!

I just put new tyres on recently, stuck with the Michelins, stock standard size on front but went with 285/35s on the rear. Wish I had done it sooner, grip is fantastic, and the look is even better. Clearance is tight on the inside corners but nothing moves, haven't had any scrubbing issues yet with a fully loaded boot. I will probably drop back to a Michelin 285/30 next time I go around but still no issues with the '35 profile.

'16 AMG C63S Coupe
Standard we have 285's on the rear with the coupe... I wonder what we can get under the rear of those.

I might have to leave it too Sanch to find out

Cheers,
Scar

285s on the stock 19"x 9.5? - I was advised that 285s won't fit by my tyre shop

285s on the coupe work a treat, should come factory for the other variants too!

You know me too well lol...

I know 295s will work but if 305s fit on to the coupe wheels I won't bother changing my wheels

Plenty of grip!

They definitely fit, have spent almost a week in them now and no problems at all. Will head back into Merc in a week to confirm there is no minor scrubbing anywhere.

Good to know, thank you!

Then 305s should definitely fit onto the stock 10.5 wheels in the rear

Haha, maybe.. The rear inside corners appear to be the clearance issue. I only have about 5-7mm of clearance in those corners with the 285/35s, which is why I will go a 285/30 next time around. Perhaps if you remove the lining you might have more luck with a 305 on a 10.5?

Unless you are talking about the Coupe, then I have no clue, it's a different **** end with the wider track!

I have a sedan and want to upgrade the rear tyres as well.

The sedan has 9.5" rears, is the coupe getting 10.5" rears?

I wonder if these 10.5" rims will be available to buy or even if they will fit on sedan.

King Monkey, can you confirm that you have 305's on the rear of your sedan and if they are fitted to factory 9.5" wheels or aftermarket larger wheels and what profile are you running, 30 or 35?

I was considering fitting 295/30/19's but it would be great if we could hear from someone who can 100% confirm that they have done this with no issues.

Yes, I'm switching my car to the coupe it is currently on order.

I'll be happy with 295s on stock

Eventually I plan to change the wheels, would be great to see what fits on the car!

It would be interesting to find out offset etc and see if they would fit on the sedan...

Yes, it comes with 10.5 - However, they are 20" in the rear.

I just checked the offsets.

Sedan rear - 9.5 J x 19 ET56

Coupe rear - 10.5 J x 20 ET57

Offsets will work with the sedan - only concern would be the 20" wheels (unless you can order the 19" from other markets) our coupes only get the 19/20 options.

Good luck and keep us posted

Do a search for this thread and look at page 5 --then read the rest as he details some problems.

+1 , I heard the limit for rear would be 275. however, some guys on here are running 285s on the rear with stock wheels, I'm not sure if that works out without any issues.

w205 c400 c63s
Hi just bought my first AmG c63s. currently owned c400 too.. i know they don't share the same specs correct me if am wrong but they have the same body i was thinking c63 has more room for wider tires. my w205 c400 is currently using 285 rears 20s and 245 front 20s i guess 285/295 on AMG sedan should not be a problem? any thoughts



my old c400 i made it look like AMG car looks so aggressive with 285 rear

285

+1 here

Went 255/35 front and 285/35 rear

Car feels great, will prob get 285/30 next time just for asthectics as the 35 sidewall at 285 is a bit chunky

No issues , it's normally only me and the Mrs. In it though , put a rugby team in the back and who knows.

You thinking of making the change?

Yes, I definitely want more rubber on the road, and I'm trying to see if I can go up to 295 with wheel change. Knowing that 285/35/19 on stock wheels work at the rear definitely helps.
