What tyre pressure?

Car has 225x40x18 wheels on it, not the original size - so what pressures should I now put in?

Play it by feel. Start 30/30 and adjust according to what feels best.

What's the most accurate tyre pressure gauge?

Comfortable and quiet on the move, enjoyable to drive. Nicely trimmed with great attention to detail. 1.4 TSI sweeter to drive than a diesel.
