Yeah like Justin said the mtn bike tires can essentially go on almost any regular rim with little modification, however there are tubeless specific rims where the spokes thread into the rim perse' and the inside where the tire is is smooth with no holes (except for the valvestem hole). On the bmx rims the little kids were using the glue on type like on your road bike. With technology they are rarely seen unless on the 18" wheels (yes 18" diam). Nemrod sounds like a pretty decent bike.
