Looking for air compressor ideas

[HaulingAss]

Any chance you have a picture of this in your smugglers trunk? I've been looking for a couple weeks for the right quality high powered compressor to throw in the truck, but I also have my mobile connector, extension cord, and various tie downs in that spot right now so curious for how much room it takes up. I'm a visual learner!

Yep, it only takes up one of the smallest of the three compartments in the smuggler's bay (with room on top for hoses).

That's a yellow tow strap draped over one of the cylinders and that black thing just right of the compressor is one of the smuggler's bay dividers that came with the Foundation Cybertrucks. It fits perfectly in there, like it was made for it, with no squeezing, binding or rattling about.

I can slide the MorrFlate inflation hose that you see on the right over the compressor and the hatch still closes normally.

Here it is in action, inflating all four tires simultaneously from 35-50 psi in only 4 minutes. The DeWalt 20V inflator would take an hour or more.

I like that air hose. It looks really flexible so you have four different hoses coming from one outlet, correct?
The air chucks are self holding? They all fit in that bag! Love it.

I love it too! Yes, the reason it works so well is it connects all four tires together, so you can fill four times as fast. The chucks are closed unless locked onto a valve stem so you can use the same hose to fill just one tire. When used with four tires at one time, you are guaranteed they are all filled to the same pressure. I run the same pressure all around, but if you had a reason to have a pressure differential between the front and rear, it can easily accomodate that simply by taking two of them off first, and continuing with the remaining two.

The chucks are the best part of the MorrFlate hose, really nice brass air chucks that lock on or off instantly, with basically zero air loss. Get the one with the digital pressure guage mounted to the main manifold, it makes everything easier.

It's also awesome for deflating all four tires at once. If you've never done this on four 35" tires, you might not realize how long it takes! I haven't timed it using the MorrFlate hose, but I think it only takes about two minutes to drop 15 psi. (which is a LOT faster than manually deflating each tire, even if you have a helper on the other side of the truck). It makes quite the "whooshing" sound too.

Would you mind posting links to your exact set up? (got the one for the compressor). I’d like to replicate the compressor and hoses and any other bits and bobs needed for this system. Also, is there something you use to easily deflate all four tires? Thanks in advance ?

Wow! I think I'm sold. Seems like the perfect set up. Will have to get that compressor and probably pick up one of those dividers as well!

Somewhat off topic question for you and anyone else who has experience - I'm dipping my toes into the off road world now that I have this truck. I've gone once so far and did easy trails but I loved it. My main reason for having the compressor is as a backup in case of a flat, but I'm also super interested in doing off roading which, as you said, is a lot easier with the tires aired down. My question is if I'm majoring in the minors if I pay to get the gear to deflate my stock core tires. Is it even worth being able to deflate without proper off road tires? Or will it still be a significant step up for me on the stock core tires?

Trying to learn slowly but surely

Really appreciate the pictures and your thorough descriptions. It is a huge help!

Deflating to very low pressure is not recommended by Tesla as these are dual purpose tires, designed to have high performance on the road. The way the belts are laid up to support the vehicle load on the road means they can suffer from fatigue failure if aired down excessively. The tire may not "fail", but it could lose some of its performance and good driving qualities on the road. Tesla recommends 36 psi as the minimum. And they should be aired back up again to drive above 30 mph for any distance.

That said, airing down to only 36 psi does offer significant benefit on irregular surfaces, particularly if the surfaces are irregular, slippery and steep. I air down to 35-40 psi for rocky trails even when I don't need the extra traction provided by more conformity (just for the more compliant ride over rugged rocks). If the surfaces are steep and smooth, like smooth rock, avoid airing down very far, you could actually lose grip by doing so (because the tread can cup). In this case you may be better served with normal pressures (or air down to 45 psi for a little extra compliance).

I've aired the OEM AT tires to 30 psi to travel through two feet of melted spring snowpack, and I could not have made it at 36 psi, not enough floatation. I know, because I tried. This is unlikely to damage the tires significantly, because the snow supports the tires sidewalls and keeps them cool. Even fine sand would probably be fine at 30 psi or below, just have some common sense and avoid high sideloads, higher speeds, and vigorous acceleration, any combination of which could cause the bead to come off the rim.

Fatigue failure, like the name implies, is a gradual process, the more miles you cover at very low pressures, the more likely it is to cause fatigue issues. You won't ruin the tires running at 20 psi, at slow speeds, for a mile while the truck is lightly loaded. But you could debead them in the wrong conditions.

As a general rule, only air down AT tires to the pressures necessary, or to moderate pressures for comfort.

I used to use the Australian made brass deflators, but the MorrFlate hose is much better. The individual deflators are far from a good solution, if you have the MorrFlate hose.

You don't need any bits and bobs, just these two items:

MORRFlate Quad+: 4-Tire Hose Kit, Up to 155″ Wheelbase – MORRFlate

Amazon.com: TC·BL Portable Air Compressor 110V,Ultra Quiet Air Compressor Oil Free and Lightweight Small Air Pump : Tools & Home Improvement

It's plug and play.

I wish someone would risk trying this 125" kit (instead of the 155" kit linked above) on the Cybertruck:

MORRFlate Quad: 4-Tire Hose Kit, Up to 125″ Wheelbase – MORRFlate

The Cybertruck wheelbase is 143" so if you go by that, it's too short. But the 155" kit feels like the manufacturer was awfully generous with extra hose, it seems like there is more than 12" extra between each wheel. I'm thinking it's sized for really large wheels when their valve stems happen to align opposite from each other.

The advantage of the shorter kit is not so much the $20 cheaper price, but, if it reaches without straining the valve stems/air chucks, then you have less hose to coil up and a slightly smaller/lighter package. Just know there is a very real risk it will be too short. I use the 155" system, and it works great.

Exactly the info I needed. Thank you for the free master class!!!

Ordered this highly rated Compressor with the 7-way Trailer Plug/BF Deal $90.06 https://viaircorp.com/products/evc88p-digital-portable-compressor

I demand this now be called "the Smugglers Bay" now! ?

I may have to have a sticker made now for the inside when its opened!

TC BL now makes a heavy duty version. I wonder if it is worth the extra cost? It's still cheaper than Tesla's version.

Thanks for sharing that, I was not aware of a heavier-duty solution. But I dont see the need for more weight and power, assuming we are talking Cybertruck tires here. The 130 psi TC BL compressor is ideally sized for filling all four tires simultaneously. I can't see any significant time advantage, just more weight, bullk and cost for very minimal benefit.
