I recently purchased a WD9 that had been in the family years ago. It is in good shape and looks good, but the rear tires are getting dry rotted and the rims are rusty from having been loaded for so long. It has 16.9-34 tires on it now, but I was thinking about putting 18.4-34 tires on it and maybe some wider rims too. Has anyone tried this combination on their W-9 or WD-9? Will larger tires and rims fit inside my fenders? The rims appear to be the drop center type like the ones on my H or M, but I haven't seen this size in any of my parts catalogs, if they will fit, does anyone know where to find them? Thanks for your help!
