In addition to what Frank said, I would also like to point out that sac_scale [1] can be useful for hiking trails. If you happen to be into mountain biking, the group of mtb: tags are also useful [2]. I'm also in favour of using the smoothness tag [3] for forestry/4x4 roads, though there is debate about its usage, and I'm waiting to see if surface:condition takes over.
