    How to figure out the Tire and Transmission Ratio Value

    Was in the throttle body section, anyone know the math on how to figure out the final value for this.

    This is the description given and this on a 2010 Xterra AT.

    [ECM] 6307 - Tire Radius/Transmission Final Gear Ratio: This is used in the calculation of estimated driving force

    Thanks
