Go to the website. You can only enter one tire size at a time (I used 30.5") but it allows you select several different rear axle ratios.
To continue on, the graph only shows final gear. You can do the same thing for the other gears (1 thru 4). This allows you to determine your shift points.
You want it such that the engine RPM doesn't drop drastically between shifts and stay in the power band if possible.
