Super 8 weigh your front and rear axles at a local grain elevator or coop, then download your tire pressure/load chart for correct tire pressures, my coach tires are listed at 110 psi max. With my axle weights and tires I am underloaded on the chart which ends at 75 psi. Interesting enough that is close to the coach data plate # psi of 75 front/ 80 rear. I started my journey home on 105 psi tires,  by the time I got to Winslow AZ. I had bled them down to 85.

My Uniroyal at max is Front 105 and rear 87, I am running 95 and 85.

When I get home in 2 weeks I will weigh it when I fuel up and let her rest for 2 weeks before I take off again.

I have a Viair compressor with it own pressure switch set at 115 psi hard  piped to the wet tank.
It will fill the front tires to 110 psi via the air connection, but is very slow.

I also have the Viair compressor with a added tank. Works great. Recommend it.

I have a air hose in my propane bay for airing up tires.

Does this work from the Aux air compressor or from the air compressor from the engine?
The only time I use the on-board air is when we're getting ready to break camp and the engine can run to be warm under load. Otherwise, at the pier, long term,I have this so I don't have to short start-up (bad for the engine and noisy for the neighbors).  ^.^d

Hey Bruce, How do you change the D2 to 130 psi?
BTW...Twig uses a portable pancake air compressor. It was a  good video, though.
Does anyone know a SPECIFIC  name brand and model of the kind of air filler that you can just attach to the stem??
Thanks

Pretty simple, I raised mine to 130 before this trip.

Get a kit like this.  Extra parts never hurt.
WYNNsky Air Coupler and Plug Kit, Quick Connect Air Fittings, 12 Piece 1/4"...
Screw a 2 male fittings (one with a male threaded end and one with a female fitted end) together to connect an air hose


Add a oil/water separator like this to keep water out.

A. Remove the top cover from the governor.
B. Loosen the adjusting screw locknut.
C. To raise the pressure settings, turn the adjusting screw
counter-clockwise. To lower the pressure settings, turn
the adjusting screw clockwise. Note: Be careful not
to over adjust. Each 1/4 turn of the adjusting screw
raises or lowers the pressure setting approximately
4 psi.
D. When proper adjustment is obtained, tighten the
adjusting screw locknut and replace the cover.

I carry an inexpensive 110V contractor's compressor and this air dryer: https://www.harborfreight.com/38-in-desiccant-dryer-with-oil-removal-filter-69923.html Have to use the generator as the inverter won't start it.

Unless you have a way to verify that the air is dry you are using you are introducing water into the tire.  Rusts the inner belts. Boom.

I've been filling tires with gas station air for over 60 years with no boom. What kind of tires do you have mounted? ;)  ;)  ;)

All my shredded motorhome tires on my Foretravel factory stores lot had rusty inner cord belts.  The coaches air outlet is after the air dryer.  I have had tires thump for long times in winter use from frozen water in the tires.  The brakes require dry air to work safely in winter.

I use Mylers non water based lube to mount the tires on the rim.

Personally I do not discount others safety related comments. 

What can it hurt to use the oem system which, for sure, removes the water vapor? 

Commercial airplanes use dry nitrogen to prevent ice forming in the tires.  We skied.  Had thumping tires several times before I switched to for sure dry air.

I had a poorly maintained air dryer on a used coach we took skiing have the brakes stop working from ice buildup in the system.

And a propane regulator form an ice ball from water in the propane tank and stop the gen at minus 30.

Had to add alcohol in a fill hose to mix the water better and put the coach indoors long enough to heat the regulator.

I have a co2 tank that I use on my Wrangler to air up after having lowered tire pressure for wheeling in soft sand. Is co2 considered dry air? or is it really wet?

When airing up tires using the engine compressor run the engine on fast idle.  If you start airing a tire before governor cutout you can completely fill the tire with no gymnastics.

Glynn, they are adjustable, remove the top cover adjustments are there. When I replaced mine l got one preset at 130 off 100 on.

Mine is 132 or so/110.  Much better brakes.  And airing the tires up is easy
