Are the tires in question Schwalbes? I recall something on Facebook where Schwalbe tires would not fit and Kenda tires would fit. Possibly all solved with the Rim Strips but I do think there could be issues in Wire sizing brand to brand as well on tires. Of course, rim sizing, rim to rim can be an issue.
I have Visc D18 w/ Dahon stock aero WTB rims on them and I can put anywhere from 1.35 Kenda up to 1.95 Kenda on them, no problem. I have not explored Schwalbes.
I expect I can put up to 2.125" Kenda on these rims. My issue is that it is a tight Fender fit at 1.95". I do put 2.125" on non-fendered Dahon Jetstream bikes. Expect 2.2 and 2.3" would also work. Different Rims however than the Visc.

Reason: Add the 2.125 info.
