My tyres were going flat on a regular basis. All four. One day, one or two might be flat. Another day all four. Sometimes they wouldn't go flat for a week, etc. So I was scratching my head a bit other it.

I live in a rural location with old dears living both sides of me and opposite me. They tend to know what I'm doing before I do, so I ruled out somebody letting them down. Then again, it's unlikely that the neighbours would pay close attention at night.

I've been told by yet another one of my neighbours that going along the potholes on the school run would cause my tyres to deflate, but surely I wouldn't be the only person on the school run to suffer from this problem. The neighbour who told me this, by the way, has always been very 'keeping up with the Jones's' and tried to pick fault with every aspect of my car, declaring that Vauxhalls are rubbish, then went out and bought one that is five years newer. What I'm getting at is that I suspect him, but I always thought that letting down tyres was a lengthy, difficult and noisy process.

Any help or advice would be appreciated.
