this is still proffesionally done
the local taxi rank uses uses the disposed carcasses, and uses a hot steel wire, from a coat hangar, to melt into the rubber, to create deeper grooves, and it is very obvious when you look close.
and, no wonder so many taxi's have blow-outs etc
I sometimes wonder whether I should permanently damage the sidewalls of the discarded tyres, so that they cannot find their way across the street to the taxi rank, and re-grooved with a hot wire, for re-use
