I have a 50ft 3/8 air hose and pancake compressor that will reach 150 psi and it does ok. I do wait sometimes to let it build back up but on the other hand it does pretty good. I also have a Tire Minder digital air gauge that I like real well.

We just use the air coupling that in the generator area, start up engine and have plenty of air.

Same here. Just use the coach air. I have a 50' 3/8 hose. Coach will air tires great.

Really fills bike tires fast too! Don't know if I would use on inner tube, might pop it.

A regulator would drop the pressure.

Thanks for the tip. I will have to play with the coach air. Right now I carry a pancake which I had in the fiver, and with an extension cord it reaches dolly and dinghy. But it weighs a few pounds and it takes up space......If I can eliminate it that would be good. Be a LONG hose though.....

I put a on/off value then a quick connect. Use it to just top off the tire presure and haven't had a problem.

I have a 12V compressor. It's Viair Model # 45043 and inflates tires up to 150 lbs. I highly recommend if you don't have a compressor on a gas or diesel coach. My diesel's front tires require 120 pounds (100 rear) and this Viair works great. Be careful they have other 12V models that will not inflate to 120 pounds.

Use 3/8 hose. Use a good neoprene hose as plastic tends to crank easily. I do carry a 1/4 plastic coiled line as well only for convenience.

We have 100 feet of high pressure hose with a quick connect for the connection in the generator compartment. The length ensures that we can easily reach the rear tires in the dinghy when it's hooked up to the car.

I have found that 50 Ft is sufficient. I went with a very pliable hose and mounted by the air outlet (had to move the horn, however), as shown by the pic.

I made a gadget as shown to monitor the compressor's pressure. When it drops below 110 psi, I dump air from the compressor tank so that it starts to charge back up. When it gets high; say 125 psi, I continue filling the tire and use a more accurate tire gauge to finally set the pressure.

This method works well for topping off the tires.

Most of you probably know, but I'll say it again; set your tire pressure in the morning before the tire heats up or you drive. Next, set the pressure of th

Next, set the pressure of the tires in accordance to the axle load (you should weigh your rig loaded) and set in accordance to what the chart says from the manufacture for the model and tire size. For four corner weighing, there is other considerations. Never use the pressure shown on the side-wall of the tire. That is the maximum allowable tire pressure for the maximum load the tire will handle.

Like Oscar, I have a compressor left over from the 5er. I really like this idea better though (and it is one less 'thing' in the basement


Question on the On/Off valve: I am guessing this is to prevent "surprises" when disconnecting the hose? Where did you get yours at?

Think I bought it at Lowes. It's the same thing they use on air compressors. Can take a picture if you like.

Thanks Skip. I'm thinking this is the item - all I would need to add would be a couple of quick disconnect fittings.

Bob, on/off and one quick connect. Used some pipe tape to make sure no air leaks. makes it very easy to hook hose up and take off when no presure on quick connect.
