I took the Hummer over the desert and it rocks. great power, great comfort, it carried all of the gear really easily. I love the cabin operated tyre pressure pumps. Just dropped it down for sand and raised it up for road. It was a bit of a bitch to add all of my electronics but eventually put a power Bus in the console for laptop and all of the sat nav gear. I was having so much fun I didnt want to stop.

As far as economy goes it used only a bit more (read 10%) than my work troopy that was following behind with the drills and camping gear. Our fuel usage was almost the same on road and a little more off road. I would reccommend the vehicle to anyone. I just cant wait to tow the boat over to the gulf country when I get a break.

How well did it track on the Simpson tracks. What I mean is, wasn't the wheelbase too wide for the track in places?

And how many people can it carry ? You must have the only Hummer in Oz that doesn't spend most of it's time with a mechanic.

It carries 4 people and its track was a little wide on the narrow tracks. In most places it was a little hard to keep on line with loose hands. But with Pwr steering it was not a battle to keep on track. If I kept 1 wheel in the groove the other was well outside the other groove and pretty good to control.

John

I came across a fella in Birdsville driving a Troopy with self inflating tyres. He gave me a business card of the bloke who supplies these toys in Australia

His name is Chet Cline
Central Tyre Inflation
Moe, Victoria 3825

Phone 03 5127 6128
Fax 03 5127 5339
Mobile 0427 110 203

It is an intersting set-up and can be controlled from within the cabin. The Troopy owner said he had them fitted for about 18 months and no problems whatsover. I have my doubts about use in rough terrain but this bloke crosses the Simpson regularly and hasn't had a failure yet, according to him.

Willem,

I came across the same bloke in the Troopie when I was on the CSR. He also gave me a card.

The system idea was great until I thought about how often I would let the tyres down and thought it was not worth the risk of ripping the pipes out. It might be alright in the Simpson, but in the VHC I could see a rock or branch catching the pipes and having a instant flat.

I am not too mechanical minded. Just switch to lower and the tyres go down. Switch to higher and the tyres go up. It has an in built compressor and a reservoir somewhere Im told.

Its 3 year old with Turbo diesel Auto. Got it mainly as a toy for towing the boat to the gulf and Kimberly. Goes like a rocket on the black top. Heaps of torque.

Half your luck mate, what a mission!

Taken a couple of Hummer's for a spin, that CTIS is real a winner isn't it. Nice to hear someone is driving something a bit different out there and also using it for what was designed to do.

Me and some mates drove a 1969 Mercedes Unimog to the Kimberley in the late 80's for no particular reason - great fun.

The actual CTIS system on the hummer is actually quite involved, with pressure sensors, regulators, driers etc etc. A complete air system for virtually any environment.
As far as the actual getting the air into the wheels from the compressor it is pretty simple. It is split into front and rear ie: both rears can be at one pressure, fronts at another with seperate gauges for both. The air is plumbed to the inside end of the front axles and then through a hole in the centre to come out in the middle of the spindle on the outside. then a right angle fitting has aflexible hose to connect it to the actual rim/tyre. On steel 2 piece rims there is a metal guard to protect the hose/connectors. Alloy rims are drilled internally to carry the air to the tyre with a short connecting hose between the spindle and rim under the hubcap.
I can provide a schematic/parts typr diagram for anyone interested.
