Use our gear ratio calculator to find the effective gear ratio your vehicle will have with a new tire size. Also calculated is the new gearing you would need in order to return back to your original gear ratio when going to a bigger or smaller tire.
This gear ratio and tire diameter chart is meant to give you an approximation of ideal RPMs at highway speed (65 mph) for three situations: fuel economy, every day driving and increased towing power.
The following chart of Tire sizes and axle gear ratios are meant to give a general idea of the relationship between the differential gear ratio and the tire size and what effect the ratio has on power output and fuel economy.
Differential Gear Ratio Calculator Use our Differential Gear Ratio Calculator page to determine the best ring and pinion gear ratio for your vehicle. Installation of the correct ring and pinion gear ratio will help optimize performance, fuel economy and overall driveability.

This chart is based on 65 MPH and a gear ratio of 1:1, on a manual transmission in 4th gear. Note: If you have an automatic transmission your RPM will higher due to slippage in the transmission and the torque converter. With an overdrive transmission your RPM in overdrive will be 15% to 30% less than indicated.
Use this calculator to determine your gear ratio and vehicle’s speed in any gear and any engine RPM for best performance. Scroll through the list of popular transmissions to find yours. Or, change input variables (engine RPM, axle gear ratio and tire height) to determine vehicle speed in each forward gear.
Lowering the ratio increases top end speed - Increasing the ratio increases acceleration and bottom end power. H T E E T T CKE RO P S AR RE > > > D E E P S D N E P O T E R O M > > > > > > < < < < < < N IO T A R E L E C C A R E T S A F < < < 0.00 1.00 2.00 3.00 4.00 5.00 6.00
Differential Gear Ratio. The gear ratio most interesting to 4x4 truck owners is the ratio between the driveshaft and axles - the differential gear ratio or axle gear ratio. It is controlled by the number of teeth on the ring vs. the pinion. A ratio of 4.56 means that as the axle turns one whole circle the driveshaft turns 4.56 circles.
The selection of internal-gear hubs in the Calculator is complete except for one a few new models whose gear ratios have not been made public, and some very rare antiques. The selection of cassettes is up to date as of February 2018 for Shimano, SRAM, SunRace and recent Campagnolo models.
