May 4, 2011 at 23:20 comment added zetdotpi I wanted a pure mathematical way to calculate a wheel diameter, but it seems an appropriate way to do this. Thanks.
May 4, 2011 at 14:46 comment added Gary.Ray @moz - my link is to another "math" problem related to cycling - I upvoted Russ for providing both the precise method, and the proper formumla.
May 4, 2011 at 2:13 comment added Мסž @Gary.Ray, that link goes to a question about calculating power output and doesn't reference tyre diameter at all.
May 4, 2011 at 2:11 comment added Мסž This is actually the only accurate way to know. There are too many variables to allow you to read numbers off the tyre and get an accurate answer. @Mike Baranczak's link to Sheldon Brown is a good discussion of the issue.
