Well giving back to so much good info I have found on the web I wrote a web based too for Calculating Tire Size, Gear Ratios, and Shift points. This can help determine a suitable final gear ratio, tire profile and transmission gears with an easy to use interface. Output is in the form of a simple text chart as well as graphic representation of the data. While not really a question, it might be useful to others as well.
