This is probably overkill, but if you wish to play with the
different ratio's and tire sizes to get an idea of what
RPM you'll run at a given speed, I created a html/javascript
program (no downloading necessary, just any browser
that is javascript capable) for such calculations a couple
years ago. Its original intent was motorcycles,
but has all the data points to easily be used for cars
or trucks. The only difficulty is you have to know the
tranny gear ratio's, and make an educated guess on
the tire circumference. (diameter times pi, many
tire web pages offer diameter of all the tire sizes, such as
www.tirerack.com). I know I would be interested
if anyone has the data for the 4 speed and 3 speed
gear ratios.....
Here's my program;
