Pretty darn good answer. I too don't really think a tank, on any small compressor, (one you'd buy for the coach as an auxiliary) would be of any real value when it comes to topping off large 22.5 or even 19.5 tires. And, in reality, I don't think anyone here is filling their tires (either of those two sizes) from "0" psi. You'd just about cook any small air compressor if you had to do that.

But, TOPPING off air pressure, from say, around 95 to an intended pressure of 100 or 110, while it would take a few minutes, wouldn't be too bad. Especially if you'd only need to do it, once a month or even less. If it's needed once a day, you've got a problem and should get it checked out. But, in any case, this is the one I use and, I think many others on here have purchased.

X2- sweet little unit, light, takes up very little real estate and was less than $100.

I think you mean Porter-Cable....who sold out to Black & Decker (ick) several years ago. B&D was acquired by Stanley Works (which also owns Delta & DeWalt).


If you guys are having to air your tires (even once a month) i'd suggest somethings up. If you had a Tire Pressure & Temperature Monitoring system i think you'd see that a compressor is unnecessary & consuming more of your time that necessary.

Im find since the install of my TST 507 system i usually only have to drag out the hose & adjust my tire/air pressure 1 or 2 times a year at the most !

This is sort of the same question I've had - how often are most people having to put air into your 22.5 tires? We use our DP about 6 months out of the year. We've been from low elevaions up and down the west coast to Steamboat Springs and from 110d to in the snow at Steamboat. I have very little change in my air pressure. In two years I haven't had to add any air to my six tires. With all the differences of where we've been, the air pressure hasn't varied more than 3 - 4 pounds. Have I just been very lucky with my tires? My tires are four years old.

I believe a 150 will do the job you are looking for. I was using a small hotdog style and it took a bit as it was limited. Add a pound or two, cycle compressor, repeat. I recently got a new compressor for home: http://www.homedepot.com/p/Husky-33-gal-Quiet-Portable-Electric-Air-Compressor-C331H/203995169#customer_reviews
Very happy! Yes I have the onboard for when I am on the road, but I like the convenience of this unit for the RV at home and for so much more!

Bought a compressor from Sear's 12 yrs ago, twin tank and it shuts off @140 psi, $450. more than enough for any truck or Rv tire.Don't take long from O to 140.

I use my onboard compressor, a good 3/8 hose and lock on inflater. Start engine and run rpm's up to about 1200 using the cruise control and resume button. Wait for air to build till blows from relief valve, then fill away. I run mine at around 100 # so no issues.
