Whether the Schwalbe Billy Bonkers fits your bike is decided by one number: the bead seat diameter, the second half of an ETRTO size. This tire is made for 4 rim diameters from 305 mm to 559 mm. If your rim matches, the only remaining question is width, and that is a matter of frame and fork clearance rather than of fit.
