Tire wear

Schwalbe Fat Frank rear tire after 3000km of tarmac usage mostly, some offroad also. The brown dot is tread wear. There is no more creme coloured rubber there. Also a structural damage is showing up. There is a dent visible.
To me that means, durability of those tires compares to narrow road racing tires. At least it is not a good choice for a touring or transport bicycle.
