When you compare the same wheel of coarse the larger wheel will be heavier. But I am talking about different brands or models having different weights. Many times yes the 20's will be heavier but between 18's and 16's of the same or atleast close width there are many on both sides of the fence. Bottom line for what my point has been here is that just the 16" vs 17" vs 18" does not automatically make the larger rim heavier. Especially when the tires may weigh less for the same overall height tire. But I can even find some 20's that weigh less then some 16's not to mention 18's.
Here is a good tread pattern study

This is a drastic change in tread which with mixed driving is 1.75 mpg. I doubt the difference in tread between a non directional and directional will yield that much.
If they would let me at work I would love to derivate two cars with 2 different set of tires to see the actual rolling resistance differences.

Who tests fuel economy at constant speed?
I have no doubt that their are some combos out there that can be lighter but the choices are very very few.

But since you can not find this out on your own here is a 18" wheel that is similar priced to the 16" that weighs 23.8lbs. This 18 like many others weighs less then that and some other 16's. The point once again is that size of wheel does not always determine weight.

dude it a forum chill out...performance and gas mileage are related. I get you "can" find wheels that are lighter in a 18 vs a 16 we have accomplished fact. I was just stating the fact that you referenced a 400 dollar OZ wheel vs a clearance cheapy.
Again the Apples to Apples part.
