How noticable is a 2lb increase in wheel weight?

In terms of feel probably not any, but I can tell you for a fact that 245/40/17 tires on 16.5lb wheels gained significant MPG on the highway compared to 255/40/17 tires on the Stock VIII wheels, and that's WITH the the heavier stock wheels and 255 tires loaded in the car, plus jack, tools, airtank, etc. for probably well over 150 additional lb. of cargo.

Were you calculating miles traveled off of the odometer or from a GPS?
I expect that the a smaller diameter tire would cause the odometer to report more miles driven that is accurate, thus inflating MPG.

I don't doubt that the skinnier tires improve MPG by weighing less and having less rolling resistance. I do wonder though how much of the MPG gain comes from the tire being of smaller diameter .
