I think I read somewhere here that the 19" wheels are actually not much heavier than the 18" wheels. It may have been from and iND which they weighted both wheels. I think the 18" rim is lighter than the 19's, but the 18" tires are heavier than the 19's. So it was a wash.
The 18s with tires, as a set, are ~7-8 pounds less than the 19s with tires.

However, the 19" tires are lighter than the 18" tires.

Therefore, the belief is that from a static weight perspective the 18s will weigh less but from a dynamic perspective, taking into account unsprung rotating mass, it's either a wash or the 19s are slightly advantageous.
