Can wheels and tires affect gas mileage?
When braking, my gas mileage is lowered by 33% at highway speeds and by 5 % around town.

Low tyre pressures will affect economy, how are you calculating the economy?

Yes, they can. Rotational mass is about 10 times greater than dead weight. That means that every pound of dead weight is equal to ten pounds of rotating weight or close to it. It is not a super drastic change but it is visible. Do not expect a huge decrease overall, maybe a half to one mile per gallon depending on what you upgrade from and to.
