Not so great news for Tesla

[Everest]

One of the first things that I bought when I got my first car in the UK was a tyre tread depth gauge.
I use them on both our cars every month. It is shocking that people can't be arsed to check something so simple.

we do that as well (though probably about every 3 months with our low mileages) - it helps identify early signs of uneven wear too.
