Best Tyres for the Mercedes Benz CLS 220

This is kind of an update after 6k kilometres and 2 years: I've bought it 2023.07, DOT is 2023.05. I store my car in a garage, and the wear is negligible. My main reason to switch to this PS4 was to improve the wet handling. With the 4years old P Zeros, the car was undriveable in wet conditions. Sliding, drifting all the time, instead of a safe cornering or accelerating. The PS4 was a dream. Glued the the asphalt. Nothing, just grip like its dry. Even when I' did a full throttle in the middle of a 90degree corner to test... Superb. But yesterday we had a rainy day, and it was the first time this year I drove my car in these conditons...and gosh i was devastated. I was sliding around in the town. Cannot do swift accelerate, cannot do a swift lane change. Car is drifting, sliding, spinning, the electronics are constantly working to keep the car on the road. And I'm not a road warrior, its not that... however when it was new, even the crazy stunts were easy(I was trying to find the limits) without even the safety electronics turning on, it was just pure grip. So all in all I'm devastated that a PS4, stored in a garage, no UV, no freeze, 6-6.5mm tread, cared very well... and its ready to be thrown out after 1.5seasons. (I use a 4 season for winter tire between nov and march, so it is almost like that im just storing the PS4 :D ) I'm really really devastated that my PS4 is dangearous in wet after 1.5-2years. This is unacceptable. Even a chinese cheap something lasts longer. (I'll skip the very price Michelins, since the PS4S on my other car cracked after about 6 years...i dont expect perfect grip after 6 years, but those huge, deep cracks...i could even see the steel inner of the tire...pathetic :( Hankook and GY is still king in this aspect. Pirelli and Michelin are only good for 1 year and testing/reviewing)

255 front, 285 back

I've mixed feelings.
GOODs: The grip in wet is pure magic, astonishing. Grip in Dry is very good
AVERAGE: Noise is fine at the front, but the back...285 wide feels a bit loud. Fuel cons is not bad, but not outstanding, Comfort is okayish but should be better according to the soft sidewall.
BAD: The move of the car. The steering is dead and wobbly like hell. Anything but agile. And the back is the same. It makes me really unconfident whether its just wobbling a bit, or the grip is lost. Makes the drive totally unenjoyable. My 245 wide Sottozero II winter tire is like a slick supersport tire compared to this, the steering feeling is superagile compared to this summer UUHP. And generally, this tire design just not working above 255 widths. The major issue is the 285 wide back.
As an UUHP, it fails. As a fairly priced grand tourer, one of the bests.
Moving on, thinking about the Assymetric 6 as a much more sport oriented traveling tire, or the SprotContact7 if I'm willing to sacrifice more silence/comfort/fuel for even better agility. (but both lacks the 285 width :( )

Huge disappointment. An average tyres with these major flaws: On wet roads, the grip is horrible. My car is heavy, and have all the electric support tools, but even in very low speeds, and very gentle acceleration, the back of the car just tryes to drift all the time. Im kind of enjoying it, but it is very dangeorus. And im talking avout low speeds. Like 25mph, average corner, very small acceleration, and just drops the back..Lilr inhave a 900Nm car, and driving on ice. The other is the noise. It has a very loud beeeeeep noise above 55mph, and getting worse and worse by going faster and faster. It is horrible, not just a very minornl stuff. It is LOUD! :(

The tyre is fine, and okay, however it is pretty useless in the wet. Or...even dangerous. I have a 2016 CLS 220d, sport package. I've used it with an average 245 wide winter tyre. The grip was fine, fuel was fine. I just put these on back(the car is a fresh buy, but the rear tyres had 1 season already on them) Front tyres...i've bought hankook s1 evo3. Setup is: 255 r18 s1 evo3 fron 285 r18 Pirellies at the back. car is fine in the dry conditions. However the back is a bit wobbly...but the car is 1800kg, so i guess its fine. But in the wet. HORRIBLE. The rears are useless. For searching for the limits... In a wet normal road (far from filled with water, just wet) And the car was trying to driftin in a simple straight line hard acceleration. Like I'M having a drift car. Elcectronics were on so there was no problems, but what thell... its just a 400nm diesel with oversized huge rears...should be 0 issues, or some minor slipping. but not drifting. 1 week later i was having a hard corner to get on the highway. It was same wet, i was having some fu, so reached the corner with 55kph. (an average car with fine tíres could have it with 65-70 easily) I did not accelerate, just wanted to check the corner. The fronts were gripped like heaven, but the back. OMG. they lost their grip, exactly like on an icy road in the winter. I've managed to handle the unexpected huge drift/spin since im used to this; and the electronics helped as well. But it was a horrible experience... This tyre cannot handle wet. this tyre thinks that wet is ice. :D The loss of grip is not progressing. Its like fine-fine-okay- and once something more swift happening: instantly loses all the grip. Tyre pressure is fine in all of the tyres. The Hankook fronts are like glue in the same situations. The replaced front-back 245 snow oriented winter ones were much stable as well. 285 rears on a 1.8ton car, with underpowered engine should be fairly good weapon in the corners, no matter what is the weather... Summary: Please dont buy this crap, if you want to survive wet conditions.

Absolutely shocking tyres. No grip and lethal on anything but straight ahead. These tyres should not be on sale they are that bad. Mercedes CLS.
