Tire Inflation - What RU Using

We ran across the same problem, with oru compressor factory set at 125 psi, it jsut wouldn't do it. Newmar has a pressure doubler or did from the factory near the compressor. Others are available, but hard to find. I've been meaning to install a Newmar doubler for years and have yet t do it. A couple or three hundred dollars and a few minutes it seems is about all that is required.

I use a home pancake compressor b4 I take off ... on the road I carry an electric compressor which takes a LONG time to fill but I rarely have had to use it. Seems like a decent compromise for someone who isn't on the road for a long time.

I use, and am highly satisfied with, a Fini AirBoss compressor. This is among the most compact "real" compressors available, and not as loud as some though by no means quiet. I have no trouble getting my tires to 80 psi with it, and without needing an overly long time to do so.

(Craftsman also rebrands the same unit.)

I use a "Slime 40026 2X Heavy Duty Direct Drive Tire Inflator" pump that I found on sale for $60. The power cord is short, but the hose is long (it takes a really heavy power cord to carry enough current for a 12V pump, that's why it comes with a long hose).

I tried using a cheap cigarette lighter pump and ran into the same problem as you -- it could barely make it over 70psi, but I needed to get to 80psi.

If you get a 12V pump, get one with battery clamps, not a cigarette lighter adapter, the cigarette lighter can't put out much current, so those pumps don't have a lot of power.

If money is no object, ViAir has some great 12V pumps, but they are not cheap.

One of those small dual tank compressors from a Harbor Freight. $45-50. Easier to move around than my larger 10 gallon horizontal shop compressor. Both 120VAC.

A 120v Porter Cable rated to 150 psi.

Ryobi battery powered air pump but I only need a max of 65. Recharge from truck's 110 plug. Powers my saw, drill and impact wrench too. Five years now.

I use a Husky air compressor from Home Depot. It goes up to 110 psi. But since I purchased new trailer tires from Discount Tires, that store has been letting me have free air from their compressor, which works a lot faster than my Husky compressor.

Viair 00088 88P Portable Air Compressor

Works great and has a long enough air hose and power leads to reach all the tires.
