|BentMetal||PowerTank all day long... I can go from 10psi on my 37's to 30psi on all 4 tires in about 6 minutes, on my 33's I can go from 12 to 35 psi in under a minute each! The PowerTank can also run my airtools out on the trail and reseat beads when they break loose... sure there are cheaper ways to go but if you do your research there is a reason they say "you get what you pay for"|

|jagerhelix||Nice, I was always curious about how much a 20oz paintball tank would fill up. Can almost be used as a little emergency air up kit if your other gear goes tits up.|

score on the arb comp!
my son plays a lot of paintball and had several 20oz co2 cylinders that he didn't use anymore. he picked me up a "fill adapter" at the paintball shop, and i used about $5 in random parts from lowes to adapt that to an air chuck. filled my 33's from 8psi to 25psi as fast as my big home compressor and i think my local welding shop filled these for me for about $5.
not sure how many air ups i'll get out of one of these (at least one). i carry two.
so... for a budget option i dunno if i could beat that. a powertank would be sweet, but if i was spend that kind of money on my jeep today, a powertank wouldn't even make the top 10 list.

I found a used ARB air compressor for $50 and made my own harness. It was ment for running lockers but I attatched a tire fill up kit thing and it fills my 31s from 18psi and my friends 33s from 18psi all the way to 32psi in about 30min

If you're interested in the numbers:
Figured against $10 air up at commercial station. If your cost is less at a commercial station, the following numbers will be skewed higher.
Based on the Powertank PT10-5200 @ $390.
Rated for 16 tires (35x12.5x15) at a 20 psi (10-30) increase with a tank recharge fee of approximately $1 per pound = $10 recharge every fourth air up. With these numbers, it would take 52 full (4 tires at 20 psi) air ups to break even on the purchase price of the Powertank, not including fuel cost to get to the recharge station.
With the ViAir 450C portable cost of $300.00, it would take 30 full air ups to break even.

I wouldn't recommend the 85P if looking at a VIAIR unit. That is just too small to do a 35" tire and will take too long. If looking for a portable solution, I would recommend the 400P from VIAIR. It can fill a 35" from 15 to 30 PSI in 2 min 20 sec.

CO2 is an option too, and all systems have their pros and cons.

I bought this one a few weeks ago, works great. Granted I only have 31's, but is at least made out of metal. I am going to mount it to my AC bracket, (my compressor is gone).

I have a VIAIR portable compressor and while it took me 10 minutes to fill up in Co Springs 2 weekends ago, it worked well just slow. I haven't tried it at higher altitudes than that though, but know it will take a little longer. Filling up from 15-34 took about 1 minute per tire back in Virginia and I miss it
I don't mind the speed though because I spent $6 on Labor day to fill up when I forgot the compressor so IMO it's better than running through all my meter change and having to replace it again.

I have a powertank. If I'm stingy, it will last a couple years on one fill. We came out of the dunes one day, this old man and his company were filling his tires with a compressor. I filled up three jeeps, and was down the road with that old guy scratching his head at me. He's probably still there putting in air.
Nice thing about it, I can remove it and carry it in my trucks. I can carry it down a hill to a jeep in distress, or I can paint my freakin house with it.

|jasongind||Those are the only (engine mounted compressors) I know of that are capable of the massive cfm's required to air up in a descent amount of time. If you have the cash they are well worth it.|

|Tshields||I have a York system on my TJ with a 2.5 gallon tank I can air up all four of my 35's in 5 - 10 minutes. Couple of weekends ago I aired up 7 tires in the amount of time that it took my buddy to air up 3 of his at the top of Kenosha pass. Yorks are more expensive, but they work very well.|

|Summertime Boss||Anyone use the ARB compressors? How do they compare to the Vair?|
|09-25-2012 08:06 PM|
|C6Rubicon||The Vair 400P will air up a 35" tire from 15 to 30 in slightly over 2 minutes per tire. It's going to be my next purchase.|

|GSPup||I'm still making a run to the closest gas station with air. $1.50 to fill up all 4 tires to 32 psi from 16 psi isn't bad IMO. Takes about 15 minutes. More important things on my list at this point.|

I had a portable compressor, until it got stolen a few weeks ago, and it worked. It was not ideal at all. It would take about 20 mins to air from 15-30 psi here in town, but at elevation (where the air is much thinner so ther is less to compress) it would take around 45 min per tire. Any compressor set up is going to run into that same problem. Even if there is a tank with it, the tank will fill the first tire then it is the compressor doing all the work.
So I will be getting a CO2 for next season. No worries about thin air, will air up 35's on 17" wheels from 8-25 psi in 42 sec each. I hate spending an hour or more airing up after a run. Just my 2 cents.

I just finally got my own system last week, The smittybuilt 2747 air system. I was going to piece one together to save money but 4wp had one in stock and price matched Amazon to 199 out the door. Comes with everything and airs up my 35 from 14 to 32 very quickly. this was the cheapest and quickest way I could get air on the trail.
But I've also seen a $40 harbor freight compressor work just fine but slow.

Air up suggestions
I've been kind of going back and forth on what to use for my air up system. I think I might just start out with a portable air compressor and see how I like it before I invest the time and energy into a CO2 solution.
Eventually I'll be on 35's with 15' wheels. I'd like to air down to 10psi and drive around 30psi.
What are your guy's experience with your systems? I was leaning toward a Viair 85p, but I figure it wouldn't hurt to see what other people's thoughts are.
