I can top off all of my tires in under ten minutes from start to get the hose out to hose back put away. And its very quite. Just my preference on this issue.

What CO2 system do you use? Just curios as I'm looking to purchase some type of air compressor and going back and forth on options.

Thanks! For those that went with CO2, did you go with 10 or 15lb system and how long typically would tank last for before needing fill up?

rarebear.nm · 11-16-2016, 02:47 PM

I have a 20 lb tank. I believe its from Powertank. I'm going into the third year on the first tank full and also use it for other tasks as well.

The most important thing about what you use to add air to your tires is that you only add dry air. I have an air dryer inline on my pancake compressor, and on my shop compressor in the RV garage. It's another reason I quit using my small 12V compressor.
This is the most important reason some choose to use CO2 or Nitrogen to inflate tires, no moisture in the gas.

Watching the video suggested above led me to a video by RVGeeks that shows the entire kit of the ViAir compressor and accessories and if you have any interest in this unit, this is a great video showing all the essential components and the storage case and system. I wish I had seen it before I bought because I would have been less worried about the purchase from Pat Bauer's recommendation that he thought it was a great unit. Here is the link.

Your only decision is which of the units you buy. I thought that I had purchased the 100% run time unit, but looked yesterday and realized that my unit has a 44% duty cycle. However, when adding 10# to each front tire, I found that it ran for 5-8 minutes per tire and the output nozzle got hot (not the motor or pressure chamber) and I let it rest ~ 20 minutes before inflating the other steer and again it ran 6-8 minutes before I shut it down. Easy-Peezy. You can see the final pressure (120-122# up in the red area) on the gauge in the last picture. Great system.

This is what I have, it's a great compressor for the rig, car and bikes. I don't see a need a low power 12 volt compressor, if I don't have AC power then it's time to exercise the generator.

This is what I bought. I thought I got a good deal at $99, now it's on sale for $69.

It's really quiet a portable.

The problem with most pancake compressors that I have seen or heard is that
1.) they are larger than the ViAir type compressors (consuming more basement space), and
2.) they are noisey as hell when they are running.
People that are concerned about annoying their neighbors need to hear what the compressor they are buying sounds like. I have a pancake compressor (Porter Cable from Lowes) and it is jarring when it kicks in and starts to run and I hate listening to it. JMHO, not what I want to take on the road....

How does it work if you need 120 psi like my front tires need? The compressor only goes to 135 and my last one went to 150 and it was slow.

Not really an issue as I have covered how to add the correct amount of air to a hot tire.

Since I have plenty of air at home and do not need to add air on the road I am wondering why so many folks find that they need to be adding air so frequently.
Pressure drops at 2% for 10F so a drop of 50Ff is needed before you need to add air to get back to the suggested +10%. Are there really so few truck stops with functioning air hoses?

Yes. Without some means of removing moisture from the air, it's introduced into the tire, and it accumulates over time. Moisture can contribute to rot inside the tire, and you can't inspect the tire inside. I paid considerable money for the dessicant/particulate filtration system on my shop air installation, which includes a 200psi max pressure DeWalt compressor I bought at Home Depot.

Disposable portable inline dessicant air dryer cartridges are also available for adding air on the road.

Something else to be aware of is that compressing air heats it. Once compressed air is added and pressure is measured, after the air cools, tire pressure can drop some, depending on how hot it was and how much was added. Not a great drop, but it can and does occur.

Finally an expert that agrees with my method.

It doesn't hurt to add air to a hot tires if you know how much air is needed when the tire is cold. 5 psi is 5 psi no matter when it is added. Check again when the tire is cold.

I have never had to add air on the road with the Entegra, but if I do, it will be adding the tire to the on board compressor system with a clip on air chuck. That would take the tire up to 130 psi before the compressor shuts off. Drop 5 psi and I am on the road. Thanks Pat Bauer for that idea.

I don't need to add air "frequently" but if you have a flat tire as I did and the Les Schwab truck gauge is wrong you need to add air the next day. I've tried using the onboard compressor way back before 2002, just wasn't worth the hassle/noise of running a 300 hp engine just for compressed air! Plus with a portable compressor I can loan it to someone three spaces over (which I have done).
