Do you mean air suspension? Not me, for sure. My experience has been that large heavy duty pickup owners in North America dabble with it when they have heavy trailers to tow. It allows them to inflate their suspensions according to the load they are hauling, particularly, it keeps the rear wheels more-or-less level with the front under heavy load. There is nothing about it that is aimed at off roading that I can think of. Mild and wild off-roaders still use shocks, springs, torsion bars etc.

Or do you mean on board air compressors? Nothing much to say about that.

From the thread title I understand that the thread initiator wants TBHP members to post pictures of their rides when it was air-borne, i.e., when all 4 wheels were in air.

As far as I know, I only understand on-board air as the quality of the air on aircrafts. But then what do I know anyway?

It may also mean the compressor setup used to fill air in tyres!

Please be a bit more specific, pvrajan

Since most off-road vehicles are generally open-top or soft-top, there is a lot of on-board air, I guess. No special set-up required, me thinks !!!

aircrafts == off-roaders

Well, you must know something, you have managed to capture a pretty nice girl type friend.

Winches and air compressors and all kinds of stuff are easy in the West. India? Hah! I am wondering if one of you entrepreneurial tycoons has thought about opening an off-road shop.

Sir Dan! Forsooth, I'll have you know that many of our shops are off the road! Some off the sidewalk even!

Many off roaders in the west used for offroading have on board air compressors.
The reason is that many times in sand/snow people deflate the tires to get better traction and get out of sticky situations(I think the Hilux has this option),
Once you get out of muck to the tarmac, re-inflation using external compressor is a bit of pain. Hence the on board air compressor where you can control the tire pressure depending on terrain.
I seriously doubt that anybody has such a setup here.
Scorpio mHawk owners have a tire pressure sensor, but no compressor.

Yup. I saw this in Dubai. It is very common there. Without that, those guys dont even dare taking their cars onto the sand.

Assuming you are talking about the need to re-inflate tyres after offroading, yes I have a small portable compressor by Truck Air good enough for 275 psi which I bought when I offroaded with my Landcruiser on soft beach/desert sand. You need to drop to atleast 15 psi to be able to drive on such sand else you dig in in no time.

I know that the military spec Hummer has a self inflating mechanism. Not sure about any commercially available offroader though.

Yepp.. Saw this deflation trick on the Top Gear Arctic circle episode. They even did a "flame" trick on the tyre to put it back on the rim. Not sure what exactly they did, but it looked cool.

Even I have a portable inflator, which comes in handy with tubeless tyres.

Many serious 4x4 people fit on board air compressors on their vehicles. Even portable air compressor usage is a pain if you have to get down in snow and then inflate the tires manually.
If you google for it, you will find kits for Land Rover, Land Cruiser, Hilux etc., in the market.
