Question Theoretically would lowering the CT increase or decrease MPG efficiency?

I was just thinking in terms of race cars I know lower cars tend to create less drag but of course they are at much high speeds.

Putting larger wheels on the car is a sure way to kill the MPG due to weight but when we lower our cars - would that increase MPG or decrease it do you think?

Ideas?

I was worried too when I lowered and adding larger tires/wheels to my hybrid but I haven't noticed any change. I am lowered 2 inches and now have 245/30/20 and 285/25/20 vs the stock 245/40/18 all around.

So the CT should be fine unless you hyper-mile

well so far with my 1.5" drop and a bigger base wheel with 205/40/18s all around, I havent noticed a dramatic decrease in miles, I seem to fluctuate between losing 2 miles and gaining 2 miles, so no big diff to me. I guess it depends on your wheels, if you keep stock wheels but lower should save gas right?

So you actually went with a more narrow tire than stock? To improve mpg?

I was thinking 225/40/18 which would be a slightly wider contact patch on 18" Volk te37 or ce28
