How to calculate the gear ratio of a jeep?
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 help you decide what is on the best gearing for your Jeep.
When to change gear ratio on XJ Cherokee?
After you’ve lifted your XJ Cherokee you’ll probably want to put some larger tires on it. If you’re upgrading to 31-inch tires you’ll probably be fine with the stock gear ratios in your axles. If you’re upgrading to 33 or 35-inch tires, however, you’re going to want to change the factory gear ratios.
What should the gear ratio be on a 37 inch tire?
If you’re running an AW4 automatic, a good gearing ratio for 37-inch tires is 4.88:1 or 5.13:1 gears. If your Jeep is equipped with an AX-15 automatic you’ll probably want 4.56:1 gears. At this tire size, your Jeep won’t be very street friendly so an even lower gear ratio than what we recommend might be better for crawling.
What should the gear ratio be on a crawler?
If you’re building a crawler you’ll obviously want an even lower gear ratio for more torque. Below is a handy chart that can be used as a guideline when decided your gear ratio. You can also use the equation of stock tire height times stock gear ratio all divided by your desired tire size.
