I made up this simple worksheet to assist in determining wheel backspacing and tire clearances. It helped me keep it in a simple one page format. Custom wheels and tires need to be right the first time. Measure, measure again. Then measure again. Just before you order measure one more time.

Hope this helps someone. If you see any mistakes, let me know. It's primarily for the rear axle, obviously.

This tire calculator helps, too!
