Portable Air Compressor

Yahoo Message Number: 56282
Does anyone know of a good portable air compressor? Recommended pressure for our Toyo tires is 115 front and 110 duals. On our last trip we were parked for 6 weeks and all tires lost some pressure and by the time we got to a truck stop they were inflated so it was difficult to get them at the proper pressure again. Thanks!

My 2003 Intrigue has a air quick disconnect in the driver's side front compartment, and the dashboard air pressure gauge says there is 120 pounds available. This air connection may have been added by one of the previous owners, but is very handy, and something I would have done myself. By my tire gauge I can get about 110 out of the system to the tires, and that takes care of the duals, and will bring a low front tire to that level.
I had to buy a 50' air line, quick disconnects on both ends, and a chuck that would fit the valve stem/wheel opening combination, and I have what I need, except for the 120 pounds needed in the front tires. For that I have a nitrogen tank and regulator to top the fronts up.
Check to see if you have that air chuck, and you are most of the way there.
To your question, the Wal-Mart type little 12 volt compressors will keep your towed up to 35-40 with little drama, but will burn up trying to fill a 12R22.5 tire.

Jack, the set-up you describe is a common factory install on our coaches. IMHO a purchased air compressor is an unnecessary waste of money. The onboard air line is the only way I've aired my tires for 4 years, with no problems. I need to air up only once or twice a year. No big deal.

Thanks, Lee, my new Toyos seem to hold air fine, and the only adjustment I have bothered with were due to temperature variations, like from 106F to 10F. I check them once a month, along with my other monthly chores, because if I have a leak, I want to find it before I get ready to go somewhere.
When I was in Phoenix I checked the tires one weekend, because I was leaving for Quartzsite. When I got ready to leave Wednesday, flat inner dual. Luckily it was just a valve stem that had given up, but still I had a tire guy come out and fix it.
How much pressure can you get out of yours? I considered upping the pressure at the compressor, but decided it was working fine, and I did not want to stress the system.

Hi Jack. 115 PSI if I recall, but that drops off quickly so you have to get the system to recycle.

Jack, as Lee writes your coach has the air compressor already on board to pump clean non moist air into your tires. You will need the suggested following;
A) 50 feet of air line, good quality hose that stays flex able when its cold.
B) fittings that match the female already on your coach
C) good quality air gauge for trucks with off set end. This is needed for the duals. I found a very good one recently with battery for digital read out, appox $25. Also, NAPA has an air delivery catalog with lots of good heavy duty gauges.
D) start your coach engine and pump brake pedal to drop air reserve so as to engage air compressor. This will fill your tanks to max reserve and when you hear the "spit" start filling your tire. With the cold inflate pressure your after that's not a problem getting there.
The one thing I like about this method is you are putting clean dry air in your tires which in my opinion is preferred. After a couple of tires and the timing of air spit/release it will go pretty fast. I have used this method for years. With the coach in storage you can expect to loose appox. 1 lb per month in a tire.
Hope this helps, let us know how it works out.

Al is 100% right on! I bought my gauge at Les Schawb (mail order) in Junction City. They have the best stuff, priced fairly. My gauge has the head paralell to the body to do both duals nicely. You might also want to consider Alligator Valve Covers (not at all expensive, just Google that name). Makes the job even easier.

Well, my onboard compressor will not inflate my front tires to 115 psi after 5 years of expermentation. The best I have been able to do is 110 lbs with a lot of time expended on the last three pounds.
Truck stop air lines do not do a good job either, and your tires are warm when you get there.
So, I picked up a used Sears version of the Porter Cable 6 gallon 150 psi air compressor that you see in Lowes and Home Depot.
This compressor does the 115 psi rather quickly on the few times per year it is needed. Others have tried 125 psi portable compressors with poor results.
My rig is loaded to the axle rating (it was designed this way) on the front and therefore must have the 115 lbs. A 120 Psi cutout on the onboard compressor is of little use in this case.
I would rather have 10 lbs of "wet" air than too little air since under inflated tires are the cause of lots of tire problems.

I'm with you Dean. I'm a fanatic about my tire pressure and my onboard air didn't cut it. I got an "air doubler" from Les Schwab in Junction City and am very happy with the unit. It gets 115lbs of air fast and no hassle. It was expensive, but worth the price to me.

If your air compressor has a governor on it, you can up the air pressure cutoff point. I upped our to 135 lbs. Then the air dryer discharges dropping the air pressure to 130 lbs. I use a air chuck that locks on to the valve stem. That way I can get the needed pressure for my front tires.

I upped mine to cut off at 150# and turn back on at 135#. Would pull the release valve when done so wouldn't keep the high pressure in the tank. Then would open the valve on the tank as to exhaust any moisture. Did this for about a year then bought a Porter Cable pancake at Lowes, works great. Think I posted a picture of the installation with a 50' retractable hose mounted in a bay.

Not much to my routine Lee, I just check my pressure everytime I get on the road. My old Toyos held pressure great, but two of my new Michelins leak a little air now and then so I have to add air after sitting for a week or so.

Thanks Dan. Do you use braided flexible extenders on the valves? If yes, they could be the source of your air leak problem.

I am considering installing some extensions on the tires to allow easier inflation. Does anyone have any suggestions which type of extensions are the best?Stan Inspire 51406

No I don't Lee. I had them on my SOB because it came that way and didn't have any trouble with them. I figured I was lucky and haven't added them to my current ride.

I use a single extension for the inner rear wheel to check the pressure and to air it up.
When that is done I remove the extension.
The extension is about 5 inches long with wire braid and it threads onto the inner valve stem without much of a problem.

The last time I bought tires, I had TDS mount the appropriate size valve so that the valves for the inner tires were long enough to be pointed out through the outer rim and were just as accessible as the outer tire. Each is 180 degrees from the outer tire's valve. These are eminently swappable, but you do have to have the tire dismounted to install them. Seems they come in all kinds of length so it was easy to get the correct ones. No more crawling around or extensions.

Steve, just after I purchased my rig in 2002, Country Coach gave me 6 new Toyo tires for free and a new sticker to put in the coach due to a Safety Recall.
The essence of the recall was that the recommended tire inflation for the Magna (and other models) was wrong, so they had to replace all tires that might be affected.
If you look at the Toyo tire inflation charts and the Bridgestone tire inflation charts and have the weight of your rig at hand, you can determine your required pressures.
Mine are and always have been 115 psi on the front and 95 Psi on the rear because I still run the 10R22.5 size tires on my rig.
Subsequent to this 2002 recall, in 2006 Toyo announced that they did not recommend their tires being used in a Country Coach/National RV application.

"In multiple recalls and internal service bulletin campaigns conducted from 1999 through 2005, the manufacturer and brand name owner, NRVH and CCI have repeatedly failed to inform Toyo about safety problems related to suspension components, and in the installation of incorrect tire information placards that led to tire failures. Based on this history, Toyo cannot be confident of receiving future communications from NRVH/CCI related to problems on coaches that have been fitted with Toyo tires."

I hope this helps clarify my statement.

I do not trust the extension to not leak air so I remove when it is not needed.
If you leave it on then you have to fasten the loose end to the outer wheel, and I don't want to do that.
The extension that I use was purchased for a Class C motorhome that I bought in 1994. I experienced loss of air on an inner tire due to the extension leaking and I did not care for the scratching of the outer wheel cover by the clip used to retain the outer end of the extension.
I would have a different opinion about this if it was difficult to screw the extension into the inner tire valve stem but it is really simple and quickly done.
