Inflation system for drive tires.

This sort of thing is widely used in some other countries. I've always wondered why you don't see more of them here. One possible problem I can foresee is air leaks. There is a bushing on every dually, being rubbed all day, then your friendly DOT inspector wants to see a leak-down test...

 

interesting, iv run a tire inflation system on my belly dump for a while that works of the truck air to inflate the tires, and been very happy with it, id love to have something on my drives as well. i wonder how well they hold up to mud and dirt and dust. and what the cost is.

 

They are not cheap. I have the setup on one truck(about 100K miles)no problems yet. Each wheel position is a seperate pump so you have 4 different pumps to fail.

 

Old news. It's a glorified CTIS (Central Tire Inflation System). The Soviets have been putting them on mining, construction, and military vehicles since the 60s, and our own military caught on in the 80s. To be honest, it does surprise me that we haven't seen companies at least dabble with such a system... I think it could be quite valuable in vocational and sitework applications, where you could deflate your tires enough to give you more surface area in contact with the ground, but not so much that it causes you to lose your bead on your tires.

 

Maybe I'm misreading the link, but this looks more like bolt-on hubcaps with pendulum operated air pumps and regulators in them. Appears to have two separate caps for checking individual tire's air pressure. Also installs in five minutes, I'm thinking it must be fairly basic.

They should chrome it - would sell more to the 'chicken truck' crowd that couldn't part with their chrome hats.

CTIS systems look interesting, but yes, are quite expensive ($5k or so) last time I had checked into it a few years ago.

 

Never seen one like that. I've only heard of Tire Boss http://www.tirepressurecontrol.com/

 

According to a news article I read this morning they will be sold by Michelin . Asperia's website shows them at $299 each . Google "halo tire inflator".
