Bob, on the 635's we do not do any 9 inch wide fittments, nor have I ever tried to do so, so unfortunatly don't know that it works. My computer tells me that it does not. I would assume that a retailer should have info about the product that they are selling. I would never sell a wheel that I didn't know if it would fit for my customers. My advice, if they can't tell you the correct fittment info, be careful about your purchase. Aaron
