TIRE SIZE CHANGE CALCULATOR
This calc can be used to find a new gear ratio.
Bigger tires can help you crawl up those slick rocks, look cool, and rob you of power. One way to compensate for this is to swap out your differential gears. The left side of the calculator requires all three entries. The right side will show the results. The New Gear
box will show the ideal gear ratio (getting as close to stock as possible). If you want a bit more power, for rock crawling, go with something closer to the Lo Gear
number. Also, the Effective Ratio
box shows your adjusted gear ratio if you choose to keep your original gears.
