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
I kinda understand I suppose. but would an extra inch really matter?
