Engine RPM Calculator. Enter your axle gear ratio, tire diameter, vehicle speed, and transmission gear ratio in the blue fields and click the calculate button to find your engine RPM. Axle Gear Ratio:: 1: Tire Diameter: Inches: Vehicle Speed: MPH: Transmission Ratio:: 1: Engine Speed: RPM
Solve for your Transmission Ratio. Solve for your Transfer Case Ratio. Solve for your Crawl Ratio. If your tires are bigger than stock you probably, like myself, have spend a lot of time trying to WAG (wild ass guess) your actual MPH when going down the road. If you know your gear ratio and tire size you can get a fairly close idea here.
Calculate your differential gear ratio from RPM, tire size, and desired MPH with this online tool. You can also find new gear ratio with a new tire size, convert P-Metric tire to inch diameter, and more.
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. Input your stock and new tires sizes along with your original gear ratio.
Enter your transmission, transfer case, and axle gear ratios to find your final crawl ratio, which is the number of engine rotations per tire rotation. See popular gear ratios for different vehicles and learn how to optimize your crawl ratio for off-road driving.
This page will help you figure out what gears you need when adding larger tires, how to calculate a gear ratio, or calculate your final crawl ratio.

This 4x4 Calculator can help you to find the gear ratio closest to the original setup. Converting from metric tire size to the more common inches used in those larger 4-wheeling tires can be handy. High overall crawl ratio means you can go slower - that transforms into better off road capabilities.
4x4 Gear Ratio. The best 4x4 gear ratio depends on how you'll use your vehicle. For normal driving and light off-road trips, a ratio below 50 works fine. If you're going off the beaten path or need to tow, choose a ratio between 50 and 79.

For example, a gear ratio of 4.10:1 means that the driveshaft will rotate 4.1 times for every full rotation of the wheels. Selecting the right gear ratio ensures that your vehicle has the right balance between power, speed, and fuel efficiency. So why does gear ratio matter for off-road driving?

A ratio > 1 increases torque but reduces speed (commonly used for climbing or pulling). A ratio < 1 increases speed but reduces torque (used for racing or fast-moving applications). A 1:1 ratio keeps torque and speed the same. Example 1: Torque-Focused Setup. Drive sprocket teeth = 15. Driven sprocket teeth = 30. Ratio = 30 / 15 = 2.0 : 1
