Yes there are huge tyre pressure shifts with temperature. On a hot day in Australia a tyre could go up 10psi while in use if it wasn't balanced. The seals in the wheel rotators are a special carbon assembly unique to this company. The rotators on the outback trucks come with a 1 million kilometre guarantee. The same hardware is used in snow in Latvia and North America. The reduced vibration in trucks on rough roads is making other vehicle components last much, much longer. Systems pay for themselves. In practice, snagged air lines basically doesn't happen. Between this Toyota and another car, I have been driving bush tracks for 6 years through the Australian High country and haven't lost an air line hose yet. Many drivers have this experience. If a hose did come off, I'd just push it back on. It is much more important to have puncture protection where I may have to stop and change a wheel under adverse conditions with standard tyres.

by any chance could you tell me what product this is exactly have been trying to find a system like this for some time now and have been unable to find one that has the fetures yours has @@YJ0AUF

From where i live (iceland) there is tons of offroad vehicles using the external hose cti systems and there has not been that many issues when it comes to snagging on trees, rocks, ice and snow and most often its "dissasembled" while daily driving with the external hose and the hose conecting to the inflator valve are in the car and installed when going on trips

@@icesar8211 We visited Iceland in 2018 for almost two months, I couldn't believe the amount of vehicles running with hoses like in this video to operate a CTIS. One question I did ask a few drivers of these vehicles was, "why do you stick them out at 90º to the vehicle body?" They really didn't have an answer except to mention that is the way everyone does it. I also asked them if they had many issues with the hoses, only one person with huge tyres on a Mercedes Sprinter 4x4 mentioned scraping against rocky walls was the only problem and if pulled out it took only a few minutes to re-instate the tube or replace it with a spare. There is one major difference though between Iceland and Australia, scrub, or low lying bushes and trees that will potentially snag on the tubes. Iceland has very little scrub in the inner parts of the island that I visited compared to what we have in Australia. However you do have a lot more sidewall scraping when navigating rutted tracks than Australia does from my small look at Icelandic inner travelling. I now have one of these systems, but it is the heavier duty truck system that is the mainstay of this company. I recently did a couple of tracks where the scrub and trees presented some real issues, the end result is that the fuel tanks on one side of the truck, which are inside the body line and wheel line have many train lines scratched into the steel tanks from the scrub and trees. The CTIS hoses deflected all and sundry and have nary a scratch, quite a testimony to the build, design and material quality of their product.

Glad to hear it worked out for you too. I have a lot of paddocks around my home that are soggy in winter. Even in 4WD the wheels churn up the mud through the grass. I punch the low pressure button, then drive anywhere in the paddock without breaking through the grass - with the firewood trailer on the back. Get to the gravel driveway, punch the Hi button and by the time I hit the bitumen I'm already topping 30 psi and rising. Super handy. I have a $2500 winch on the front of the car that came with it - but I haven't needed it yet. The CTI works every day. the winch, maybe once in a blue moon.

Can i get a rough estimate of how much it would cost? Am trying to install the set up but i don't think am gonna find it in my country, might have to ship it and have it installed here.

will 2nd the request for a rough cost... cheers.

@@anthony-joedib8583 hey mate, sorry I only just saw your comment lol 18 months ago it cost me AU $ 5300 to have them supply and install on a Jeep Cherokee, I liked it so much that I got a job there about 7 months ago lol the system is around AU $ 4800 supplied only, we do ship around the world and if you can wire up a trailer with 5 core wire cable and hold a couple of spanners... you can install it yourself, cheers mate

@@sn0wchyld hey mate, just got notified of your comment.. the system is around $4,800 supplied in Australia... if you can wire up a trailer and hold couple of spanners, you can install it yourself, it's proven to me that it worthwhile on the traction point but also in tyre wear and cost, I've done 60,000 in the 18 months since I put it on and tyres aren't even down half tread yet. cheers mate

Yes the tyres are maintained to within a pre-selected range, usually 2psi. I haven't run a stopwatch, but anecdotally I don't believe it has taken more than 2-3 minutes to get from any pressure to any other pressure. The compressor works well, without any air tank. The rotators seen here are a lower-profile version than those used in trucks, but manufactured by the same company. Bear in mind that the large truck tyres are often in groups of 4 or 8 and higher flow rates are necessary.

@@YJ0AUF Thank you for your informative reply. Yesterday I visited their factory in Morwell, I intend to get this system. Mine will be for a 7.5 tonne 4x4 light truck, so will be sightly different to your set-up, but essentially the same.

Hi, a fair question. It should be ok. I have seen a couple of different strategies at work. Where the air line line comes from a point in a wheel arch, the approach to the centre of the wheel is kept as close to horizontal as possible. This gives maximum travel with the wheel. On bigger vehicles I have seen semi-rigid air lines pass over the wheel anchored to a bracket mounted on the suspension arm, so that the entire feed floats up and down with the wheel, then there is a protected air line from that bracket back to the vehicle body, like the brake line does. I have seen this done to some light trucks as well. It is very effective.

@@YJ0AUF Thank you very much for your prompt and thoughtful reply. I sent a message to the CTI team just now to learn more about the system. I’ve tried a few manual systems over the years, and look forward to learn if I can make this a reality for my Jeep camper in the US. Best to you and yours. Ofer

You're welcome Ofer. I think you would get a lot of value with this on your jeep. It sounds like a marketing plug, but I do use this all the time. Sometimes I'm just towing a trailer over a bit of wet grass and the wheels want to churn. I just push the middle preference and find that I can then drive anywhere without kicking up mud and scaring the field with tire marks. I've noticed that in Australia, most of the companies that send trucks into paddocks to spread fertiliser and the boom lifts operated by power companies all run CTI now. They don't damage crops where they drive and it keeps the farmers happy. At least the AUD-USD conversion is on your side right now! Cheers.

The parts used in this clip came from AIR CTI, an Australian company. aircti.com

kzfaq.info/get/bejne/jMCWiqRmnp3Vc2w.html He has a full video of the van

@@davehart7943 Thank you, for dropping the link! 😊

It is a 1985 L300 van with a 2.6 petrol-LPG engine

@@agalah408 thank you!👍

The 4WD L300 was originally manufactured as a hybrid. They took the suburban L300 van body and put it on a full-length Pajero chassis , with all Pajero suspension, transmission, diffs, hubs etc. It is quite heavy, at just on 2 tonne unloaded. Very tight turning circle, good approach/departure angles and as a forward control vehicle, it is easy to get wheel placement just right in tough spots. Not many of them left now.

we have done that, but only on trailers because the axle is hollow and can be utilised like that, drive axles and steering axles have to many moving internal parts that don't allow for it to work like that unfortunately

Only on portal axles.

The company that creates these systems is in Morwell Victoria, Australia. They do installations and have support agents around the country. They fitted the system you see in this video. I believe they have fitted around 2500 vehicles so far. Mostly trucks. You can find them at aircti.com/

Search for AIRCTI AUSTRALIA and you'll find them. They are in Victoria.

@@spudboy1328 Thanks, i went with a system from Iceland. It will be ready this weekend.

This is a very very common "civilian" method. It's not unique to just this video.

It would appear you clearly did not watch the full video. The author states how long has he been using them in off road conditions, with no issues. Also, there is nothing dangling.

@@bm_videa Yep. This is not a new or unusal way of doing this. I think he's just new to this kind of setup :D

...I bet it ain't cheap 🤨 ..hopefully someone will make an expensive system soon, made from Chinesium, from Chy-na

@@Texaca yeah, whenever marketers fail to mention price its a red flag.

I think they are about $4K (AUD) It is all Australian made hardware, including the electronics.

@@agalah408 Sorry to burst your $4K. I am keen to fit this to my 519 AWD Sprinter (6 wheels) when MB finally delivers it sometime mid 2024. Last year I spoke to AirCTI about costing their unit for a 419 4 x 4 Sprinter. (4 wheels). At that time they spoke of $9K plus ARB twin compressor plus installation (~$2,000). With all the rampant inflation atm, it will be over $10K plus range now.

@@davidlewinsohn9252 Thanks for that figure mate. 10k is a bit hefty for some festo tubing and a box with solenoids.

I believe it is around $3000 USD for the kit, plus the cost of a compressor if one is not already fitted

@@agalah408 what’s the name of the system?

@@flight2k5 AIR CTI is the brand. They have been making this kit for a long time and dominate the market in Australia because of their tough hardware.
