I was planning on going on a tad smaller tires, due to having already large tires as standard but now I'm wondering...

You are probably baffled because there are two different concepts.
1. Lowering a car to achieve aero is NOT done by reducing the tire size. (Because they know reducing the tire size hurts the gearing) Cars are lowered by lowering the suspension.
2. reducing tire size INCREASES the rpms of the engine. That increases gas consumption.
3. THe SLIGHT increase in height is more than offset by the deceased rmps of the engine at highway speeds.
There are numerous threads on this topic where you can get a fuller understanding.
