For all of you who are wondering what adding different sized tires/rims to
your van will do to the outer tire (tread) circumference, speedo readings,
and odometer readings, I have an interesting little program that will
calculate those effects. If you want it let me know and I'll e-mail it to
you (it's only 29kb).
