E36c_AMG

I bought this type of rims:
Specifications:
Size: 20x8.5 Front / 20x9.5 Rear
Bolt Pattern: 5x112
Finish:Forged gun powder Face
Offset: 35 Front / 35 Rear
Hubcentric: 66.6

Original AMG says that these tyres must go front 255/35R20 rear 275/30R20 but i want to know can i put wider tyres without any rubbing or speedo/ESP problems?

I`ve got AMG 8,5x20 front and 9,5x20 rear -- tires 255/35 and 275/35 as per OEM on my -07 S550. I think this OEM setup works flawlessly for driving.

I am soon to replace tires and found that the widest tire this 8,5 front rim will take is 255, so i am leaving this at the 255/35.
But i do think it looks a bit weird with this low sidewall tire in the front as the rears are a bit higher.
Found out that the rear 9,5 can take an 285/30-20 so i am considering a more similar height sidewall using this 285/30.

I don`t want to jeopardize the way the car feels like on the road, especially in the the twisties. So I am curious if it will induce any noticeable tendency towards understeer using this lower sidewall & greater width tire at the rear when mounted on the same wheel width --
Though - the 9,5 is the narrowest wheel this 285/30 can be mounted on and this may counterbalance any tendency to more understeer somewhat because of the little more bulging sidewall generating a bit more "give" sideways.
Hmmm...come to think about it - it may not look nice with that "bulge" at the rears, so maybe best leaving it at the OEM dimensions afterall....but the greater width will for sure give it a better rearview look..

Anybody who have tried this tire combo on this OEM wheel dimensions and can give any advice about looks and the driving feel ?

Best setup is:

20x8.5 front w a 255-35-20 and rear is a 20x9.5 w a 275-35-20

Thanks Jason - nice car on those pictures :-)
I believe the guys at the MB factory know very well what they are doing and recommending this setup for a reason.
As for tires i had the Michelin AS3`s on my now sold S320 (w220) and i must say that they are - hands down - maybe the best tires i have driven on, all things considered.
So when my Dunlop Direzza D102`s are gone i will treat myself with buying the new Michelin AS3 + for my S550.

On my Porsche 928 S4 i have Conti DSW and are to some extent pleased with them, but they are a bit to "mushy" for a heavy sports car.
On my w124 E280T i have the Hankook Noble 2 and are pleased with them also --- but i am biased to the AS3`s

We have lots of bad roads here and with lots of turns and nothing beats the Michelin AS3`s. As an extra plus they lowered the fuel consumtion by approx 0,7 dl pr 10 km compared to the Conti DW Extreme which was so unstable that I sometimes thought my wheels had come loose. They were a nightmare to drive as one had to correct the cars line constantly - in heavy crosswinds they were almost shockingly unstable.
