So to the point of "rotating weight", this is more commonly referred to as "inertia" and would apply more to flywheels than to wheels and tires.
Yes, inertia is your enemy and you are proving the point: Tires and wheels are exactly like extra flywheels at each corner of the car - They are mass the engine has to keep accelerating throughout the whole run. Less mass is a faster car.

I agree, as I stated earlier they are four flywheels. And not only does our vehicle have to accelerate them, it has to decelerate them too.
And they located at the four corners, much worse than the actual "flywheel" which is extremely idealy located!
Light wheels are a huge issue. The autocrossers know this!
