One thing you might consider is the more air in the tires, the less rolling resistance.

Yes you are 100% correct and less rolling resistance equates to better fuel mileage. Now isn't that what we are all striving for, better fuel mileage??
The less rolling resistance is due to the fact that you have a smaller footprint in contact with the road. The smaller foot print means less tread on the road which equates to more tread wear down the center of the tire which means the tires wear out faster, have less road contact during braking and steering, especially so in a panic stop or maneuver, the tire has less flex and therefore could be damaged more easily when encountering potholes or debris in the road. Over inflated tires cannot isolate road irregularities such as potholes, tar strips, expansion joints as well as properly inflated tires causing the vehicle to ride harsher and transmit more noise into its interior.
So if you want to sacrifice all of the above and more for less rolling resistance just to save a few pennies on fuel than by all means go for it.
