Just be cautious and dont take this as gospel. It would be a decent rule of thumb however. Unfortunately it doesn't (and cant') take into account wheel width 6.5 - 7 - 7.5. Nor does it take into acoount the differences from tire to tire even in the same size.

For example:
215/45/17 Kumho Ecsta MX = 24.7"
215/45/17 Dunlop SP 9000 = 24.5"

And I can attest at that .2" sometimes can mean the difference between riding sound free and rubbing a little bit! So this is a great rule of thumb, but it would still be wise to get the real specs on the tire.
