Well... Yes the Michelin Pilot Sports A/S3+ is an "Ultra High Performance All Season" tire. It's all those things. 80MPH is MOST DEFINITELY it's forte. These are autobahn tires so cruising at 120 is even it's forte... while it's raining...
As far as minor shaking or vibration it could be a minor wheel imbalance or a resonance issue. Road surfaces have a texture, that texture causes a tonal resonance due to how it transmits via the tires, that resonance turns things into a shake or vibration when it matches other parts of the car.
If it's bad enough that it interfers with your driving take it back and complain. If it's not the A/S3+s will smooth out after 1k miles (and then get noisy again after 10k miles).
