I just added the ARB dual to my truck which runs 37x13.5-17"s that I run at 50-55psi for the street and ~25-35psi for trails. I'll see how quickly it can air all 4 back up soon. I also have a Viair 450P that I was using previously (with 35x12.5-18" tires, same pressure ranges) and it was actually pretty quick to air all 4 back up from 35-55psi (maybe 10-15 minutes). However, on a trip where I went down to 25psi, and brought them back to 75psi (I was towing after the off road section of the trip) it took 10+ minutes per tire, and I was giving it a few minutes to cool between tires so it took over an hour total. Anyway, I added ARB lockers so I needed a built-in solution and went with the ARB dual.Personally I use the ARB dual compressor. We air up our 33’s in no time. And I’m not sure a of pump that can do a better CFM, or is as reliable as the ARB.
I suppose it all depends on what pressures you run. Some folks are running 35"s and only running 32psi and only air down to say 18psi, others might be running 80psi on the street and go down to say 25psi so that's a big difference. I have 10lbs Powertanks in addition to the compressors I mentioned above, and they are definitely way faster. With my WJ it was just a matter of seconds to go from around 18psi to 45. I haven't used one on my truck yet. Either way, I think 30 35" tires from one charge is optimistic. Here are charts from Powertanks:I had done a lot of research on this, but meet a guy camping who showed me his 10 pound CO2 system. It would probably air up 30 35" tires with one charge. No moving parts. Nothing to burn up. I just bought the parts and am putting it together today. Something else to consider.

Thanks for the clarification. It is all about the volume and change in pressure. Great chart!I just added the ARB dual to my truck which runs 37x13.5-17"s that I run at 50-55psi for the street and ~25-35psi for trails. I'll see how quickly it can air all 4 back up soon.

So, with a 10lbs tank with a 35x12.5-17" if you're only adding 10psi (say 25-35psi) yes you should get ~30. However, if you're adding 20psi that drops to 16.

Good call on the Morylate, I actually have their setup too and agree it's AWESOME to just air up all at once, and end up with perfectly balanced air pressures (I usually let it sit for a min or two once I close the valve and stop airing up). On full-time 4wd vehicles like my WK2 Trailhawk it's especially important to match pressures well.

I second this…the Viair 400P might get a bit hot and take its time, but it’s well-constructed and the hoses that come with it are also high-quality, unlike some others (looking at you, ARB).I use this kit-it is strong enough to reinflate 4 35s with no break and has been reliable. It may not be the fastest on the market but I do think it is a great QPR.

I’m thinking of using a Milwaukee M18 electric 2gal compressor. It’s 40lbs and bulky……but prolly work on anything and have the capability to run air tools along with other cordless tools.
Anyone else haul a full size compressor around? Worth it or no?

Lol, funny cause it was your rig that I thought about when I saw it at HD!! Then said to myself “it could fill most tirs really quickly”. My Viaair takes 30 mins for all 4 tires from 20-40psi. I want it to be more like 8-10mins.I’m thinking of using a Milwaukee M18 electric 2gal compressor.
