They are also available in a couple of 451 sizes.
Comets are commonly used on recumbents ridden on the road.
They're 406 sized. From the responses I've gotten, it sounds like my concern about putting the narrower tires on the existing rims is not actually much of a problem. I've been using vittoria randonneur tires for touring on everything from rail trails to close-to-sheets-of-broken-glass, and have never had a flat yet, so I'll probably try those on his bike, as they come in a 1.5" width.
Thanks!
