Hi all:
With all the discussion regarding tire sizes and the potential effect on
speedometer error, I thought some of you might find the following web site
interesting. You can plug in your tire size and see sidewall, radius,
diameter, circumference, and revolutions per mile. Additionally, you can
input a different tire size and compare the changes in all the above
measurements. It even provides a graphic which "demonstrates" the difference
in tire size. Cool!
