I used to fly V bombers which had tyres which wore down to the threads as a matter of course. You wore off several layers of rubber and threads before the tyre needed replacing. They were however different to modern tyres, being inflated to 325 psi. The tyres usually looked horrible and I was told on countless occasions that the aircraft's tyres needed changing by people who didn't know how they worked.
