One minor correction to the above information, which is a moot point since the OEM wheels have been swapped out- - - -a 17.5 inch wheel is for tubeless tires with a very radical taper to the bead seat and a short, stiff sidewall, not a "split rim". They are the same height as a corresponding 16" tube type tire on a 3 piece rim.
