. Only thing i didn't like about them was the sidewall. Reminds me of The Great Wall of China... 
Thanks Michelin!

All was good. 14K miles later....time for some more.

From what I understand that was the VERY EARLY production and the problem was resolved sometime last summer

Sorry I wasn't trying to hijack the tread.
Tire pressure 32psi in front and 34psi in back?? I think.

An old High School buddy works at Michelin product developement in S Carolina and says the drifting problem was actually with the Pilot Sport A/s(built for European roads without a center crown) and was not an issue with the PS2
Here is Michelin's "Official" Response:
"In North America, roads have a slight slope towards the outside of the road built in to evacuate water. Unchecked, this road slope or "road crown" would normally cause a vehicle to pull to the right. Vehicle and tire manufacturers design in a slight left hand pull for North American applications to account for road crown. This characteristic in the tire is known as Residual Aligning Torque.
In original equipment programs, tire manufacturers work with OEM's to achieve the perfect Residual Aligning Torque balance between the tire and vehicles. The OEM specifies the amount of left hand pull for the specific original equipment tire. Replacement tires, on the other hand, are designed to match a broad range of vehicles and therefore employ an "industry average" approach to drift. Depending on the specified drift for the original equipment tire, some vehicles may be more sensitive to alternate, replacement tire fitments. Some Mercedes customers experienced vehicle drift after mounting Pilot Sport A/S tires. This does not reflect an issue
with the tire or its manufacture but points to an application issue - one of matching tire drift to vehicle drift. To accommodate Mercedes customers, we made a very slight modification to the Pilot Sport A/S to increase the level of left pull and eliminate the sensation of drift due to the road crown.
You may view a Mercedes Star Bulletin on Mercedes STAR Tekinfo for a bulletin concerning this issue. This bulletin, states that the Pilot Sport A/S is now approved for Mercedes Vehicles.

Hong Kong has been under heavy rain storm in past days; so I did not want to upgrade the Rosso to PS/2 yet. Incidentally, I saw some PS/2 tires and I guess it is supposed to be ZR but not sure if the letter "Y" (stands for Heavy Load) does matter or not to be on C55 ? Or should I be getting something else ?

I did ride C55 under signal 'yellow rain' on pretty flooded roads, risky but very exciting. Amazing a rear drive car like C55 can perform so well on flooded roads...may be the low rev torque gives good grip even drive slow?
