Tracktype is a measure of how well-maintained a track or other road is, particularly regarding surface firmness. It usually applies to highway=track but is often used for non-tracks too, especially in less-developed places where many main roads are unpaved. The proposal from which this key originates may be found at Proposed features/grade1-5. The proposal was voted on, but was standardised primarily because of its widespread use.
surface=* refers to surface material and sometimes to material structure. It may suggest a track type sometimes, but because the same surface material/structure can exhibit various degrees of firmness, it is still advisable to add tracktype=*.
smoothness=* in addition provides a classification scheme regarding the physical usability of a way for wheeled vehicles.
How to map
tracktype=* is primarily used in combination with highway=track (around 96% of uses) but it has also noticeable usage on highway=service, highway=path, highway=unclassified. This tag is useful to provide info about road quality, especially for unpaved roads.

May be applicable to heavily degraded and crumbled roads which was paved in past. Often also tagged with surface=gravel;compacted;fine_gravel etc. |
|||
tracktype | grade3 | Even mixture of hard and soft materials. An unpaved track. |
|||
tracktype | grade4 | Mostly soft. An unpaved track prominently with soil/sand/grass, but with some hard or compacted materials mixed in. |
|||
tracktype | grade5 | Soft. An unimproved track lacking hard materials, uncompacted, with surface of soil/sand/grass. |
