I just got these and I think they are great!!.. and right now Michellin is running a really price on them b/c they are brand new tires, eventually the price on these tires will start going up.

Placed an order with TireRack a few moments ago....
245/40ZR18 (Fronts) $256 ea
275/35ZR18 (Rears) $295 ea
To my door for $1150.06
General "search button consensus" seemed to be that the 275 would fit without any rubbing issues on an otherwise stock '06 E55.... so it seemed like a low-risk gamble on the rears.
Overall diameter comparison:
Fronts: 25.71"
Rears: 25.31" (stock 265 width)
Rears: 25.55" (using 275 width)
As you can see, the stock setup actually has a smaller OD on the rear tires than the front (0.4" smaller), so stepping up to the 275 rears actually makes the front and rear diameters more consistent (0.16" shorter in rear)
All of these diameters were taken straight off Michelin's spec sheets BTW...
Tires arrive next Monday at the latest, installed next Thursday (9/9).

PSS have great handling. They look fat if you aren't dropped.

This how it looks on a C63 on stock suspension. It sure does hold the ground though.

They The Absolute, just put them on my S55K w220, and on my S65 w221, they seem to work better than the PS2's for the ABC suspension, in my opinion. Lets hear some more on this,
I will need a new set of tyres soon, currently have the Continental fronts good, rears 20% for my E55k W211? Anyone got the PSS on an E55k W211, kindly let me know, your opinion.

ps.Let me know if your car has an issue with this setup,Mine was turning traction control on in 3rd gear at 70-80 mph.
It was driving me nuts and I fixed it by lowering the rear tire pressure 5 psi and it fixed it.

The PS3 is a "Green X tire" from Michelin and not meant as a true performance tire. Tire Rack has only five sizes (and all in 18")
"The Super Sport is intended to deliver significantly better performance than its predecessor the PS2 approaching that of the current Pilot Cup Sport, but with better wear and wet traction characteristics. The new PS3 will fill the lower end of the performance envelope and sizes (18" and below) currently filled by the PS2, with the Super Sport providing the OE homologation fitments for Porsche, Ferrari (in particular the 458 Italia and the 599 GTO), As well as BMW M cars and Mercedes high performance models starting in 2011 when the tyre will also become available to consumers to retrofit to their cars."
Why not the PSS instead of the PS3?

I was thinking of your issues when I did my research before placing my order. I don't know enough about the ESP system to understand why traction control would be activated at high speeds. If it were purely due to diameter (relative to some pre-programmed stock value in the ESP) then it seems like a lot of these guys running custom 19" and 20" wheel setups would be reporting issues all the time.... Some of those combos seem to be significantly taller than stock diameter.
My best guess is that the ESP is comparing the wheel speed sensors at all 4 wheels and looking for variations in excess of 10% (or whatever) between the front and rear sensors. Large speed differentials are interpreted to be a traction issue of some sort and ESP starts to interfere.
What is weird, is that a large rear tire causes slower sensor readings (less tire rotations per mile) so compared to the front sensors, the rear tires would appear to be "dragging" not spinning to the ESP system.... Maybe in that situation, it's actually pulsing the FRONT brakes in an attempt to slow them down relative to the rears?

I'll be careful to check tire pressures and set them to factory specs, then hope for the best....

I think if you end up with a big differential between front and rear sizes then you will end up with trouble. If u upsize the rears you need to do the same proportionally to the fronts

A few "money pics" for those of you still wondering what they look like....

I went with the slightly wider rears....man, they look HUGE in person! They get mounted on Thursday, and the car gets detailed on Friday. I'll post up some beauty shots after that.

So what happens when someone like GregMB puts the 275/35s on with stock front sizes? Does this have any negative consequences?

Think about it this way; even the variation in diameters from a new tire to a bald tire (stock size) varies by 5/8".
Stock size: (265/35-18) = 25.31" with 10/32" tread depth...once that tread is worn off the diameter is only 24.685"
That's a diameter variation of 2.5% on the SAME tire from the time it's new until it's finally bald and ready for replacement. To me that suggests that the diameter needs to be significantly larger than stock before the problems start.
What brand/model drag slicks was Skratch using? I could look up those specs to compare.....
BTW -> according to that 1010Tire site, the difference between the 265/35 and the 275/35 sizes is only 1.06%

After talking to kleemann they say there is 3% limit that the car can adapt to.
That is also why I added more air in the fronts because it started doing it again but now its ok with 38 psi in the fronts and around 33.5 in the rears.
The slicks I have on the rears are 25.6 and taking air out honeslty makes a difference.Once after 75 mph it gets even worse and the second im on boost the tc light blinks in 3rd gear.
Today the car was a beast and the light was on only in second gear like before.

So according to Kleeman is the car looking at variation between front and rear tires?
At first it this issue seemed to be concerned only about rear diameters and difference in size relative to stock. If it's as simple as maintaining a 3% tolerance from front to rear, that will be relatively easy to accommodate.

Yea its looking at front and rear and the faster you go the more out of range it gets and kicks in TC thinking something is wrong.
It could be just my car tho but who knows.

NICE!
I should be all set then.
Stock Size: 265/35-18 = 25.31" (Michelin PSS spec)
-2% = 24.80"
+2% = 25.82"
Going to the 275/35-18 size = 25.55"... comfortably within that range.
My only guess is that the slicks are "growing" a lot more than a conventional radial tire at higher speeds...?? Are you running stock size fronts?
There are plenty of guys here running the 275s out back, so there has to be a secondary explanation for what you're seeing....

Do you think I'll need spacers with the wider 275? I'm not sure how much clearance there is on the inside of the wheelwell... there's seems to be plenty on the outside edge.
A 10mm spacer would emulate the CLS55 wheels almost perfectly (they are 11mm different), but nobody seems to make a hubcentric 10mm spacer.... I think the smallest I've seen is 13mm??
