Tire size changes with speed and weight, weight changes with downforce, downforce changes with speed, winds, air temperature.
Maximum theoretical speed on a dyno, sure.

It's not like the tires can expand in diameter 200% though. I'm sure that Michelin has parameterized tables for the tire's mechanical behavior that they are confident about by now. They aren't exactly new to tire engineering...
Your high school physic teacher is on line 1. Wants to talk to you about what "weight" means...
Weight is the force the earth needs to provide to support the car. Mass remains constant except for burned fuel loss.
