When you get larger tires you have to lower the gear ratio to preserve fuel consumption. 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.
