On my xtp the rear air shocks say 150psi max so I would assume the compressor would not have a problem getting up to 40 psi but it would probably take a long time. I would be worried to run it that long. I used mine to raise the air pressure on all four stock tires from 3 psi to 8 psi and I didnt time it but I would estimate about 8-10 min of constant running and I felt the compressor after it was quite hot. If I had to fill a truck tire I would do it in stages and I would just give it enough to get to a proper compressor.

I filled an ATV tire from flat to 8psi in less than a minute with my on board compressor. Just wish I knew how high it would pump to.

 

Its limited to low ATV pressure.

 

I'm not saying your wrong but could you please explain how you know this. Have you tried it? I'm curious as to how the shocks get such high pressures and it will fill an atv tire to 25 psi. Why not a truck tire? What makes them different besides the obvious. I just like to understand the way things work.

 

I blew a bead. I pumped on my tire till it popped on. When it popped, I was over 25 lbs in it. Might have been more, but gauge stopped at 25. That was on my 1K XMR.

 

If your talking to me, I'm not arguing. I think it could go to 35 or so, if you wanna wait that long. The compressor seems great.

No I was talking to diesel dad or anyone with an explanation of how it works. I did see that video the other day and I put a ratchet strap in my box and told my friends about it. Excellent tip for new guys like me.

 

Cool. Thanks for watching.

My answer comes in a couple of parts...let me explain.

1. The compressor lists for $600, the air suspension module for $260, and the air suspension sensor for $116. I would not "want" to use my ATV's compressor to pump up a vehicles tire. This is because of the extra strain it would put on the compressor due to the automotive tires much larger volume and higher operating pressure.
2. My trucks (2009 Dodge 3500 SRW) tire pressures are around 60 psi on the front and 80 psi on the rear.... so my answer was from my standpoint when I first commented about ATV's only. I have a heavy-heavy duty air compressor in my truck's toolbox for this purpose.
3. My owners manual says this: "NOTE: Usually, to properly inflate an ATV tire, the proper ACS suspension setting should be ACS 1", Page 96. The manual also says that the tire pressure needs to be between 5 and 7 psi, Page 138.
4. I did my own little test to find my ATV's ACS capability:
With the ACS on a setting of 1, my tire pressure filled was right at 5 psi when the compressor cut off.
With a setting of 2, it cut off just above 7 psi.
On a setting of 6, my hand got too tired trying to holding it on to the tire gauge because it was taking so long and I released it and rechecked the tire pressure and and it was at 20 psi. The compressor ran for a few more seconds, filling the air line, and I feel that it had a ways to go before it shut off just from the line pressure. Based on that , I have no doubt that it could go to a higher pressure.... but my arms got too tired to find out.

In summary, Yes, it can be used to possibly seat a ATV tire bead or even fill a car or truck tire.

Would I do it .... if I had to..."yes" because "you got to do what you got to do"....
Would I do it frequently..."absolutely not" because "I want it to work when I need it on the trail!"

 

Thanks for the great info! I surely would not try to inflate a car tire unless it was flat and I absolutely had to. Even getting 20 lbs in would be enough to get you out of a jam. I think it's a fabulous accessory to have.

 

Completely agree. Only did it cause I had to.

 

I swore I saw a sticker my fox acs shocks says 150 psi on them? Does this mean the compressor can do a 150 psi?

 

I found a page in the service manual that list the air control suspension settings and possible pressures.

ACS 1 - 8 psi
ACS 2 - 15 psi
ACS 3 - 30 psi
ACS 4 - 55 psi
ACS 5 - 70 psi
ACS 6 - 85 psi

The manual also said:

"Never inflate tires above the recommended pressure"

But has no reference about what kind of tires, reading the description it says that the air system is divided in two with one compressor, one system to handle the shocks pressure (ACS) and another to handle the inflation hose, so you can go higher on your inflation hose without affecting the actual ACS setting.

 

I just carry one of the cheap little 12v air compressors with cigarette lighter plug that I got for $10 at home depot. Have used it and that way I don't have to worry about damaging the expensive stock compressor or parts. I would hate to have to fill a tire and it cost me $1K in repairs. But like others have said, do it in stages and let it cool and I think it would be fine. Not abusing them and maintenance has served me will with breakdowns or expensive repairs on these CA's.

 

I have put several tires back on the bead trail side with mine, including most recently 1 of my 31" OL1's. I would say it is certainly well over 20 psi.
