Tire/ wheel as rotational mass is NOT sprung weight, it is unsprung. Wheel hub and brake caliper are also unsprung weight, but not rotational mass as they are static, obviously.
On the other hand, flywheel is a heavy rotational mass, and it is sprung weight as the entire engine and transmission.
Anyway, lighter wheels/ tires reduce not just rotational mass to help acceleration (as if you gain more power) and braking but also unsprung weight so that suspension reacts quicker to maintain grip. Basic, simple and relatively cheap way to get more out of the car.
