Pardon my ignorance on the subject, but I am in need of faster performing equipment for airing up and down my tires. As of January this year, I have become the lead computer engineer for the world's largest operational telescope, which is located at the top of Mt. Graham in Arizona. The drive from my home in Tucson takes about 3.5 hours to the summit, with the majority being highway. I normally air up to the maximum pressure listed on the sidewall (35 psi for my Toyo MTs in 35x13.50x15 on the Bronco, 45 psi on the Toyo ATs in 30x9.50x15 on my Mountaineer). The last 20 miles or so of the drive up to the summit are offroad and many times the road is in terrible condition. I found that airing down to 18 psi makes the drive much more comfortable up to the summit. The return trip has me pull over to air up using my Viair 400P compressor. While the compressor itself does a fine job, I'd love to have some equipment that allows me to set the desired setpoint pressure and let 'er rip. This would afford me enough time to kick back with a pint for the return journey, which is almost always well deserved since my presence at the summit basically means that something is seriously wrong with the telescope.


My Bronco has tubular bumpers and I was thinking of installing some QDs on the rear bumper to turn it into an air tank, pre-pressurize it to 100 psi or something. Unfortunately, the Mountaineer is pretty stock in terms of bumpers, but the smaller tires also means that it's faster to inflate. Any recommendation on gear/mods I should consider?

 

i have twin viair 44c compressors on each truck plumbed into two 6 gallon tanks on the 02 diesel, and 3 6 gallon tanks on the 88.
i have not put onboard air in the new F150 yet.
the pressure switch is set to turn compressors on at 90 psi, and off at 140.
i can remove all 4 tires with an OLD Ingersoll Rand impact gut without the gun ever slowing down.
same for putting them back on.

 

Get one of these, connnect set and forget, they have 4 memory settings. Get the 8 AH battery or even bigger. Get the adaptor from LockNFlate. And then get the LockNFlate open flow clamp on air chuck. I have that set up and it works awesome.

LockNFlate 90* open flow.
Whole show minus batteries. https://locknlube.com/products/milwa...41873775034452

All M18 batteries. https://www.redtoolstore.com/search?...=M18+batteries
NOT sure if the Forge HD 12.0 fits their inflator, I would think it should...

Might as well get this thing to, since you will have the batteries on hand. https://www.ebay.com/itm/33577836456...BoCeVYQAvD_BwE

18 PSI...you better drive careful or buy some beadlocks.

What brand of tubular bumpers? Add QD's to them, can be like building a very unsafe device. But buying a rear bumper/air tank...meaning buying one already designed and built to specs, is a safer way to go. But when that tank is OUT of air, its OUT. Unless you plum your under hood air compressor to it.

 

Or buy this 200 PSI and 14/15 CFM bad boy. https://hornblasters.com/products/xd...hoCQkkQAvD_BwE

We use portable compressors. Be aware, these require the 4 tire manifold. Inflating one tire at a time, is too easy and cooks the comptessor.
