Dakar car question.

Add or subtract air.
Regards Philip A

Yes the Central Tyre Inflation System Image Could Not Be Found it is a wonderful feature, the ability to raise and lower tyre pressure on the go to suit the conditions is priceless.
I've also isolated the other three and kept the air pressure up to the one with a leak to keep it up till I reached camp and the repair gear.
My Humvee wasn't fitted with it (very few military Humvees are, only the Yank equivalent of the SAS vehicles have it) and I had to scrounge most of the bits, drill the spindles and fit all the air system but as I said it is a very usefull accessory.
I made these steel plates to protect the air lines as the standard protectors are only sheet metal and aren't strong enough.

Surprisingly the 75 x 420 x 5mm plus the bolts and tubes spacers don't affect wheel balance but actually help, the truck has never run smoother.

Have a look here:Air CTI Australia They distribute central tire inflation systems. Also on youtube there are some interesting movies as to what these systems can do in trucks e.g. TireBoss

Hi Lionel,
As others have said, tyre inflation/deflation on the fly.

Interesting technical aspect of the Dakar, only two wheel drive vehicles are permitted to run the system.

The co-driver gets punted out with a gauge if the four wheel drive competitors need to adjust pressure for the terrain.

Before someone comes along and says "Yes but Robbie Gordon's Humvee has them on the back wheels"

Yes he does, but an odd part of Robby Gordon's Humvee is that it is two wheel drive!

That and its 7.3 litre petrol V8.

Thanks everyone, will look further into this system.

Cheers....Lionel.
