I assume your tires are 37"s? Measure and see what they really are. Rolling radius is height from the ground to center of the hub, if you want to calculate at trail pressure, this is where to compensate. I am guessing 19.75" is a typo. I would guess those numbers to be about 36.25" and 17" instead
To get the calculator image, take a screen shot (alt + print screen on PC's if I remember) and post the image. That will make it a lot easier to see whats going on.
