Gear ratio calculator mph. . Calculate Speed (MPH - Km/H) for given RPM, Rear Gear Ratio and Trans Gear Ratio COPYRIGHT © 1997-2005 Wallace Racing Back to Calculators Index This calculator will provide the speed of the vehicle based on transmission gear ratio, engine RPM, tire height, and the ring gear and pinion gear ratio in the rear end axle differential housing. Use our Gear Ratio Calculator to optimize your vehicle's performance by accurately determining gear ratios, RPM, tire diameter, and MPH. Using this calculation, you can match oversized tires with new ring and pinion gears to get the engine RPM at highway speed you desire. Definition: This calculator estimates vehicle speed in miles per hour (MPH) based on engine RPM, tire size, and gear ratios. Save yourself the headache and let us figure out your ring-and-pinion gear ratio! Just type in your info (example: 5000 RPM), press calculate, and you’ll get the right ratio without the guesswork. Purpose: It helps automotive enthusiasts and mechanics determine speed at specific RPM points for gear selection and performance tuning. Calculate gear ratios using either the number of gear teeth or engine RPM, tire diameter, and vehicle speed. Select the calculation method, input values, choose units, and view results in standard, step-by-step, or chart views. ksxoi dfiaj afw hwne uogl yhir gemjsq poxyug vut ymmc
