Rotational inertia increases proportionally with mass, but increases exponentially by the distance from the center of the wheel.
With identical weight,a smaller wheel is easier to spin than a larger one.
You're lightweight 18s need to be lighter to compensate for the larger diameter, and even lighter to reduce rotational inertia.
Someone might correct me but:
I = m × d²
