Most tires on the summit site (book at least) show you how wide a rim you need to run that tire. If that doesn't work, I would call a manufacturer and find out directly. You can get spacers for a lot less than rims, or if you know any machinists, they should be able to make some for you pretty easily. I'm one and a spacer would be pretty basic to make. Can't believe how much they charge for something so easy.
