I average 13.76 mpg, this is taking ineffect of the tire change. I have an excel spreedsheet keeping track for the past year.

I drive mostly short distances within 5 miles, so thats why mpg is low mostly because of my gears, I need to change them.

3 speed auto
1995 2.5L
Speedometer Not Calibrated
4.0 t/b, t/b spacer, and K&N cone filter

Before on 30 inch tires and 4.0 t/b and spacer, I was getting an average of 17.1 mpg and also I think that I was driving mostly highway at that time
