Smile Airing up tires with onboard compressor and other portable devises

Does anyone use the Birds air system to inflate the tires?
If so please give me particulars (hose type, length, ends) so i can get a hose with the appropriate ends.

Thanks
Ted

Default Tire Airing

I use the compressor on my BMC to inflate my tires all the time. I bought an inflation hose 25 feet long (not the cheapest one but one as I recall that goes to 300 lbs and is lightweight, I think it is poly urethane), put on the standard ends and use it with a long straight stem tire inflation tool so I can push it on the valves pointing out and pull it on the valves pointing back. Don't get one of those cheap curled air hoses (usually yellow) ; they kink a lot and I didn't feel they were very safe. I found a mostly straight end inflator tool is better than one of those more angled ends because I have to go back through the holes in the wheel and the angled ones won't go on to the valves pointing back at that angle very well.

I inflate the fronts to 110 lbs cold and the rears to 100 lbs cold. Sometimes my wife gets inside and hits the brakes so the air pumps up again. It sometimes takes awhile for me to get to 110 lbs if we don't do that.

I have Michelin tires with Pressure Pros and find I don't have to add air often. I don't use any extensions and they stayed aired up right on the money usually for 3 months or more. If the weather gets colder I sometimes add a little more. I have a Haltec Tire pressure gauge and although not cheap (as I recall about $40) it works great for those high pressures. There may be cheap good ones but I couldn't find one.

I run 125 psi in my front tires and got tired trying find more than 110 psi when I'm away from home. Now I carry it with me. I have installed a Haskle gas booster and regulator in my roadside utility basement compartment. I can use the engine or the 110 VAC auxillary compressor to rapidly fill to about 110 psi. The booster will then bring the pressure up to 125 psi in just a couple of minutes.

The air hose fitting on the bus is larger than the fitting on my air hose, what's up with that?

Ted,

I use the engines air compressor to add air pressure to the tires on both my 'Bird and trailer, so I carry enough length of 3/8" 300# burst pressure air hose to reach all the way back to the farthest tire from the air female coupler in the house battery compartment on my 'Bird.



I use this type of male and female fittings;



When purchasing the air hose keep in mind that some hoses can get very stiff in cold temperatures, making it a little difficult to coil back up for storage, usually the less expensive hoses are harder to coil up.

I also use a grooved dual foot tire pressure inflater, that can be pushed straight onto the tires valve stem and then slightly tilted down and it holds itself onto the valve stem threads, then removing it is done easily by slightly twisting the inflater clockwise and it comes loose, this saves me from having to hold the inflater on the valve stem for an extended period.





I also have a smaller pancake type air compressor like this one below mounted inside my trailer that also has a maximum output of 150 psi that doesn't exceed the 'Birds air pressure gauge maximum and it also doesn't start to build air pressure until below 125 psi, yet it still handles airing of the tires and other on the road uses very well through an external female air coupler mounted on the tongue of the trailer.


It can be powered from a heavy duty shore power cord and plug on the trailer on one end and the buddy plug off of the generator, so I can leave it attached to the 'Bird if needed. When stopped or here at the homebase it can be plugged into other shore power sources if it is needed and used to air up the 'Bird from my other external air hookup on the passengers side, this also will air up the suspension.

Please post photos of both of the fittings, so we can determine what you are dealing with.

Our air hook-up is in a bay on the driver side.
the female fitting is the standard size, But it does not look like John's picture, 3/8 rubber high pressure hose , some of the cheaper hose cracks & will not coil, tooooo stiff, especially when cold.

I had the same problem with the BB QD. It is a little larger than all of the QD fittings on my hoses and air tools. When my local hardware supplier couldn't find any male fitting that would match up with the BB fitting, I changed it out so everything I use has compatible QD fittings.
