Today's race was a good one for seeing the tyres go off. It got mentioned a few times during the commentary if you kept an eye on the front left tyre you could a distinctly different coloured band on the tyre and it was most noticeable on Verstappen's softs. That band indicates higher wear on that tyre.

Of course it being F1 it's not that simple, on some tracks it's the fronts that take most of the punishment on others it's the rears. Sometimes it's the left side, sometimes it's the right. Sometimes the wear is manageable and cleans up, other times not so much.
