A tire gauge can be one of the best tools you have for saving money on gas. Underinflated tires produce drag, so your car has to work harder and burn more gas to maintain the same speed. So get out your gauge and check your tires every few weeks, and refill as necessary. Don't go by the pressure printed on the tire itself, though. Your car owner's manual should list the pressure you want.
The Department of Transportation estimates that you can get up to a 3% improvement in fuel economy by keeping your tires properly pressurized, which adds up over time. Taking care of your tires also means they last longer, another area of savings.

I recommend a highway tire for your best gas mileage. The strength of a tire is referring to the tread size, the larger the tread the larger the tire. Hence, the less gas mileage obtained.
Maybe, the manufacturer optimized the tire size to the vehicle, if your currently running larger than stock tires then you could be decreasing your mileage. Check the inside of your drivers side door for a placard with the correct tire size and inflation.
you may have changed the tire size which will give you incorrect mileage hence causing an erroneous gas mileage reading.
A tire can effect your gas mileage by a lot. If you do not have a inflated tire you can get 2-3 mpg less than use usually get.
Probably, especially if the other dimensions are the same as the bigger tire. Be advised that you will not receive as good gas mileage.
