## Gear ratio chart

Divide the Ring Gear tooth count by the Pinion Tooth count to get your ratio.

Gear Ratio Chart. One of the most important aspects of building any vehicle is choosing the proper gear ratio for the wheels and tires. Often overlooked, a set of gears with the right ratio can transform a vehicle from a commuter to a powerhouse. Here is a complete bicycle gear ratio chart of the most commonly used bicycle chainring and cog sizes. Hover over the cells to highlight and see the gearing information. Gear Ratio Chart. JEEPHUT GEAR RATIO AND TIRE SIZE CALCULATOR. When you change your tire size you need to make sure you have the right gearing to get optimal fuel economy and power. A good way to calculate this is to multiply .12 by your Jeeps tire diameter (Example: .12 X 38" = 4.56). Here at JeepHut we have a made an easy to read chart to Gear ratio tells you how fast the driven gear in a gear system will spin relative the driver gear. You find it by dividing the number of teeth on the driver gear into the number of teeth on the driven gear. This gear ratio formula works even for complex gear systems with one or more idlers. 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.

### 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.

Tire size, transmission ratio, final gear ratio, and engine. RPM at cruising speed must be considered. This chart assumes a manual transmission and a final drive   Utilising a number of gears from a gear chart that pertains to your bike set up (e.g. wheel circumference) and your strengths is the first step in securing the  Gear Ratio Chart: Step-by-step.
