Air Compressor airing Class A 19.5 tires

I would say there is little to consider if you're buying a compressor just for the purpose of filling your tires. First, they really only need to be aired up every few months, if that often. Second, you don't need a storage tank type compressor to do so. Third, why buy something so big that it takes up a bunch of space.

The Sears model listed here. is perfect for filling tires, even 22.5's. I timed mine and it takes about 1.5 - 2.0 seconds to add one pound of air. Since it's being used to just top off the tire, it doesn't need to be that quick or powerful.

When choosing an air compressor you have to first consider
1) what is the max air pressure I need to achieve in the tire
2) what size tank should I get?
3) what is the recovery time for the compressor?
To pump up a tire to 100 psi, I would suggest a compressor that would be able to pump up to 125 psi, minimum
I would suggest a tank size of 2 gallons minimum
cfm of 2.5.
Of the above, the higher cfm at a higher pressure is the key to the recovery time in use. Most cheaper compressors recovery at 90 psi is much lower than 2.6 so as you get close to the 100 psi in the tire, the compressor will labor to achieve that last 10 lbs or so. The Kobalt that the OP mentioned meets and exceeds all of my suggestions.

I carry a Sears huffer puffer.

As for the Kobalt line.. I have several products in that line, no complaints, but .. The warranty is better on the Sears unit.

Very good choice. The one thing that makes that unit a better choice than similar units is the 2.6 cfm at 90 lbs. Very good recovery at high pressure. I have used mine for several years and I did a lot of research on units of similar size before choosing this one.

Bry,

That is the compressor that I carry. No problems airing even large tires.

That is the compressor of choice for many MH owners, of all sizes. There is now a different brand that carries a 200psi rating if needed, but the 150 seems adequate for everyone that uses one.
