You are not paying attention.
One of the members here, IDK, has a link to a manual in his signature block. I just looked at it, and it surely does have the correct tire specs for the Classic, Roadster, and Touring.
Search for any posting (he has a thousand or so) by him, and you can download the 23MB manual.
Alternatively, order one in hard copy -- comes with a nice binder -- from your dealer.
