I suppose road surface makes a difference. Mine are now 2'308km old and they don't look worn and still feel perfectly fine. I also have hookless rims as the wheelset I wanted was HL so I said ok whatever. They recommend the Schwalbe or the GP5k S TR and since the latter is always sold out, I pounced when I saw the Schwalbe Pro One TLE in 28mm. And actually, they also came stock with my bike where they have 3'407km and they also still seem fine.
