the very limited availability of suitable tyres (which came from a pre-phones Nokia in Finland IIRC).
That'd be Nokian - they still make tyres. In any case, they never really got to a full 2.0" wide and for that reason were never really seen as (or ridden as) mountain bikes. Personally, when I bought my first disc equipped mountain bike about 15 years ago it didn't take me long to build some 700c road wheels, or much longer than that to put on cross tyres. From there it was only a matter of time.
Why? It's something you should really try and see for yourself.
