Just to be clear. They are all the same width and when it comes to measuring tread width, that isn't straight forward. The data points above are from Tire Rack and this is how they measure tread width.

That's the Uniform Tire Quality Grading system (UTQG). It was created by the US National Highway Traffic Safety Administration.
The Treadwear rating indicates how long the tire lasts. It's a number starting at 100 and goes as high as 800+. The way you read it, is that 200 means the tire lasts twice as long as a 100 rating. There isn't a standardized way to measure this between tire manufacturers, though, but 100 rated tires are fast wearing track tires that are about performance and not longevity. For comparison, the PS4S and comparable street performance tires are rated at 300, so the PS4S roughly lasts three times as long as the Cup 2. Performance tires are generally 100-300, all-season 400-700 and touring 600-800+.
The Traction rating indicates wet braking, measuring the ability to stop on wet pavement. Possible values are AA, A, B, C. AA being the best. Again, the PS4S is AA. The Cup 2 is known to not be as good in the wet, so hence the A rating. Still not bad.
The Temperature rating measures heat resistance. Possible values are A, B, C. It's speed related heat resistance. A means it can withstand temperatures and speeds above 115 mph/185 kph. B is 100-115 mph, C is 85-100 mph. But the tire's separate speed rating is more useful, especially when it comes to the Y and (Y) ratings on performance tires.

I never made a notice about that in aaaaaaall the many years. i was thinking thats only something for the race guys by use for race track because SC2 is more for that.
~ special feature from michelin.
I check all other tires to see if they have this Uniform Tire Quality Grading system too or is this only for tires sold in USA a must have ? EU etc tires has similar as i know but its not printed on tire but more a special notice for selling.
That's really interesting.

And to add as I just remembered while answering your other thread about spongy feel at high speed, not all tires have a UTQG rating. Specifically, dedicated winter/snow tires usually don't.

Section width should come from the Michelin data sheet. That's a standard measurement that tire manufacturers provide. But tread width is measured by Tire Rack, because there isn't an official way of measuring it. You could double-check the section width measurements on the Michelin data sheet in case there's a typo on the website.

i talked to Michelin Company.
They told me super sport with mo1 production stoped.
It sounds they inter them completly soon.
So i will take the sport cup 2 .
Michelin specialist told me they produce them minimum till 2030.
i noticed my old guy super sport warm up quickly in cold temperatures (8 C) too. if warm no easy drift possible.
