I had a bad experience using 700x38C Schwalbe Snow Studs on Mavic Open Pro rims [19mm width?]. They mounted fine, inflated fine, handled the test ride around the block just fine. I ride to work and they rolled off the rim about halfway there. I had to keep the inflation pressure down to 20 psi. My new wheelset had 24mm wide rims [some Mavic touring rim], and I haven't had a problem since. My experience is, when in doubt, go with wider rims.
[Side note: HED's new Ardennes road racing wheel has a 23mm profile, but is designed to work with 23C tires. The idea is that the tire will have a less upright profile, thus firming up the sidewalls and making cornering more predictable and reducing rolling resistance.]
