Rick, Thanks for posting the web site..... I have been thinking of larger dia. wheels, which would mean changing tire sizes. So this might come in handy..
I also under stand that if I go to a non-stock speedo, that I can calibrate the speedo to match the tires...
I want bigger wheels and tires to fill up the fender openings but, now I can look at the different sizes and know what it does to my speedo.
Thanks again,
Lewis
