    What is the best gear ratio to run for larger tires? When you increase the diameter of your tires, your vehicle's engine has to work harder to turn them. Naturally, this will lead to increased fuel consumption and reduced performance. So, when upgrading to a set of larger tires you should re-gear your rig to regain this lost acceleration, performance and fuel economy.

    Find your original tire size and gear ratio using the chart listed below, the intersection should be your approximate RPMs at 65 MPH. Then find your new tire size and follow it across to the closest RPM to your original tires, this will be your gear ratio choice.

    This chart is based on driving at 65 MPH with a 1:1 gear ratio and a manual transmission in 4th gear. Please note if your vehicle is equipped with an automatic transmission your RPMs will be higher due to normal transmission and the torque converter slippage. In overdrive your RPMs will be approximately 15% to 30% less than indicated.
