simple way to think of gear ratios
3:21 will give you the very best mileage when empty, but it will only pull a Harbor Freight sized trailer
3:55 will not give you quite as much MPG as above, but it will pull a larger trailer
3:92 loses a bit more MPG, but accelerates real quick & will easily pull 7,000, while climbing a grade
=================================
Going with a larger tire circumference also changes the gear ratio, but you would need a mathematical formula to figure it out.
Lifting your vehicle cost you MPG
