There is the optional surface=gravel tag to indicate a gravel surface for 
a track.
A related tag for paths, rather than tracks, is width=narrow.

See 
http://www.free-map.org.uk/freemap/index.php?lat=50.84&lon=-1.42&zoom=14 
for some example rendering of  tracks/paths of different widths. 
Everything on there is a permissive bridleway (route accessible to horses, 
but):

the magenta dashed lines enclosed by grey dashed lines are tracks
the magenta dashed lines without the grey lines are paths
the narrower magenta dotted lines are narrower paths

I have chosen not to show gravel tracks differently but it could easily be 
done.
