Auto tire deflate/inflate

Give the folks at Tire Pressure Control up in Canada a call for your central tire inflation needs.

Gee, tell us what you really think! Let it all hang out! lol
Seriously an on board air compressor can break...expensive...like all the navigation stuff. I’ll keep my HF unit and my iPad Forest Maps.

At one time the H1 Hummers had that feature.

Very few trucks ever go off road. Of those, most are not serious enough to mess around with tire pressure (yes, I understand the benefits but for light duty off road they just don't)

Most do back up on a regular basis.

Manufacturers are well aware and offer options that people will use.

I would like a dash button that lowered my rear tires for daily driver use or raise hauling loads. Better yet a knob or sliding bar, that let one set the pressure. Every time Costco rotates my tires, I have to sit there and let the rear back down from 80 PSI before driving off their lot. I have even showed them the pressure chart that at 45 PSI the tires have a 2470 lb capacity, 4940 for a rear axle that weights around 3300-3500 pounds. No go sir, door jam says 80 pounds for rear tires!!!! And I say, do you think the rear axles is at it's rated 7,000 lbs right now???

Agree with the OP on "...Screw the 18 stinkin useless cameras and navigation BS...."

But, am okay with a bicycle hand pump, electric pump, etc and had them when off road a lot

Best was just a 10 gallon tank with a Schrader valve filled up to 120 PSI

Aired all 4 over sized, flotation tires back up enough to run on the highway till a gas station was found. Then finish airing them up

If the OP is filling air bags...they don't take much air...IMHO

That is low on my priority list. On the other hand, air adjustable height suspension is very high. Since that requires a compressor it should be easy to add a manual tire inflation feature while at it. I don't foresee ever wanting the added complexity of auto inflate even if it was free. I just wouldn't use it that much.

I would love the feature and would gladly pay for it. Between having to go off road at the farm, deer lease, and the beach it would get used.

Another benefit is that I would be able increase my rear PSI up to 80 when towing and back down to 50 when not towing for a smoother ride.

Curious...

Anyone know how these work ?

Either a seal between the rotating tire/wheel to a stationary air line on the hub somewhere.

Or, a tiny pump inside the tire cavity hooked up to a special Schrader valve. Assume a counter weight 180* apart.

One per tire

Bluetooth interface

Or is there an extremely nifty design ?

Too many parts to fail for me to consider

I am in the, it would be a useful feature camp as well.
That said, I also prefer simplicity and reliability and a central inflation system sounds like the opposite of that (years down the road).

But from a general consumer level, average intelligence/mechanical aptitude perspective, even if you base it solely on the small sample size group here on rvnet where folks "should" be a bit more saavy given their hobby is towing or hauling, you'll find that the average person is lucky to know "how" to put air in tires, much less how much and when and why.

So unless the central air system was also automatic and load sensing, it would result in plenty of screw ups by the trailer backing assist crowd! lol

To answer the question though, yes I'd trade 360deg cameras, trailer assist, braking/steering assist, TPMS nanny, massaging seats and a host of other useless cr@p for central air. Absolutely
