@CrazyJames - Tyre width and pressure go hand in hand. Yes, 80-90 psi on a 23mm is bad/flat/slow/puncture prone. I don't recommend anyone do this!!! 80-90 on a 25mm is correctly inflated. If you're running wider 28mm, you could go even lower. If you're on the heavy side, go a little harder.
@Donut! - like most things in life, don't knock it till you've tried it :-)
