Can anyone suggest what the pipes are that run to the centre of the wheel hubs.

My guess would be tire inflation/deflation lines. This allows for the tires to adjust air pressure to terrain conditions.

Steve, I think they are for inflating and deflating the tyres. I'm sure if not somebody will put me right.

John,
Thank you for your response.
I too wondered if they are for adjusting the tyre pressures whilst on the move.
Central tyre inflation systems are not too common on civilian vehicles, especially a 4x2 wrecker.
Regards,
Steve

They are definitely for adjusting up or down the tyre pressure , you are correct in that they are normally seen on army type trucks , this is an old system , you wouldn't see the lines in newer systems
