For ways used by mountain bikers, mtb:scale might be better:

http://wiki.osm.org/wiki/Key:mtb:scale

It's a far better thought-ought scheme (by analogy with sac_scale) and 
the images used reflect the descriptions.  For example, I used to live 
along something similar to 
http://wiki.osm.org/wiki/File:Mountain-track1.jpg and it was regularly 
used by all sorts of wheeled vehicles, not just the "Car with high 
clearance, light-duty off road vehicles" suggested on the "smoothness" page.

An example that I did (see the "No tracktype would be appropriate" 
section at the eastern end) is Long Causeway near Sheffield:
