I don't know.  With mountain bike rims being the same width as many
road rims, but using 2 inch tires, it seems there shouldn't be any
problem with fitting a fatter tire on your narrow rim... except that,
at the same inflation pressure, rim stress increases with tire size.
Maybe these rims are too thin.  I am not familiar with them.  I use
Mavic MA-2's and they work well with most any tire except possibly
spaghetti thin 700-18's.
