Differential Gear Ratios: How to Pick the Best for Your Off-Road Vehicle

When installing oversize tires on your vehicle, you’ll notice that you’ll lose low-end power when towing, taking off from a stop or even on the trail. To regain this power, you’ll need to re-gear your differentials. The formula to figure out ideal gear ratio is stock tire size divided by the stock gear ratio.

This should be equal to your new tire size divided by your new gear ratio. However, this doesn’t account for extra rotating mass of the tire, just the dimensions.

Going strictly by this formula works well for street driven trucks without heavy aftermarket accessories. If you’re looking to get more torque for carrying heavy loads, towing, or if you spend a lot of time on the trail, you’ll want to pick a ratio that is deeper (numerically higher) by one or two available ratios than what the formula suggests. This typically ends up being between 5% and 15% deeper.
