so you are saying that 18 inch wheels that are 8.5 wide and weigh 19 lbs are less performing than 17 inch chrome rims that are 7.5 wide and weigh 30 lbs?

yes - according to the laws of physics (I=1/2mr^2)......a 17 inch that is heaver will still spin faster than an 18inch that weighs less.

not if the overall diameter is still the same...... Bigger rim, thinner tire. smaller wheel, thicker tire... = turning diamter of both = same.

Furthur more: If two wheels weigh the same, but one wheel has more mass placed on the outside of the wheel than the other, that wheel will spin slower (take more energy to rotate).
So, you can't judge a rim just on how much it weighs and it's size....unless you have some tool that can measure the distribution of the weight throughout the wheel.
Right Sprintmax?

Even though the OVERAL diameter of the wheel and tire doesn't change, the weight and distribution of that weight does change. Simply, it takes more energy to rotate and maintain rotaiting a heavy wheel than it does a lighter wheel.

It's like this...
Size of rim does not matter. Overall turning diamter (size of rim + tire) does. Weight does.
Peopel say size of rim matters because "usually" "most" 18" rims are heavier then 16's and 17's.. yet, there are many that are quite light. Also, 18" tires are heavier then the others ones as well, but if the rim is really light, even with a heavy tire, it will still be quicker, then say, a heavy 17" rim with a tire.
