Tyres...

I've done just over 11000 miles (that's nearly 18000 kilometres) and the tyres are starting to look a bit worn. The rear was replaced at just over 5k following a puncture, so tyre life would seem to be around 12k front and 7k rear.

At least, it is the way that I ride.

That's using the UK standard fitting of BT 020 tyres, by the way.
