I've searched for anyone doing this and haven't been able to find anyone who has. This usually means there is something I am overlooking with my idea. I am putting a york OBA system, with one of the primary uses to be to fill my tires. I am running a 110 - 145 psi pressure switch. The idea is this: For filling the tires, put an air regulator along with a lock-on tire chuck that I can set to whatever psi I want in the tires. This way I don't have to switch between the chuck and a gauge and the tires get the same pressure. I'm thinking I'd also run a safety pop-off downstream of the regulator to make sure I don't blow up a tire in the explosive sense. So, is there something I am missing with this?

Pete,
I'll chime in with an opinion. The York is a very capable unit if you select the correct one and if you have it installed properly. Normally, you can fill a tyre in1 or 2 minutes so I don't really see the need for what you are describing unless you plan to fill all the tyres at the same time. If that is the case then you can rig up (or purchase) one of those octopus rigs with a central inflation device and 4 or 5 hoses going to each tyre. There is a guy on the web that sells a complete kit at a reasonable price.

Your issue is that pulling all those hoses and connectors out of the storage box and rigging it up will take longer than the ~8 minutes to hit each tyre with the York.

Let me know if you want a link to the octopus rig. I can't remember what he calls it... maybe a hydra or something like that. A clever Google should get you what you want.

You just want to be able to "set it & forget it" while airing up, right? so you can just BS with the rest of the guys and don't have to kneel over every 20 seconds to check pressure? I think you got it covered, the regulator should do it.

A blow-off valve that was plumbed in a T after the regulator would be an additional safety.. like if it was set at 40 PSI, and you're airing up to 35 per the regulator, if for some reason your regulator failed you'd hear the blow-off valve start hissing away when the tire hit 40, which would make you come running for sure.
 
I do that same thing with 2 air hoses. Works well especially with lockers. I find that if the tires are filled to the same psi, I get less kick back.

I agree with the too many hoses comment made earlier. Its a bear when it takes 3-4 minutes just to set up your air. I find two only takes about 30 seconds. Then I can BS.

I dont use a York on my 60, but do on my Heep. This system works well with my electric pump on my 60 as well.

I was thinking about setting up and all tires at the same time thing, but it looks like it would take up a lot of space. Also, it doesn't look like they use a regulator on that 4-air system.

Another idea I just had is getting an adjustable regulator with a downstream vent, so when you set the regulator pressure for lower than the tire pressure, it acts as a deflater. Not sure if I want the tangled mess that would soon become that setup though.

I was just thinking of having, a quick connect with the regulator and a little hose on and then the chuck, so all I had to do was connect the quick connector, and put the chuck on.
 
If you put say a 40psi regulator in the line, your tyres will be filled at a much slower rate, right? ? ?

I really don't see how this is going to work.

Besides the novelty factor, I don't think there's any real advantage to doing this.

Having run a York on my old 22R-E for about 5 years, I can say that in no time at all you learn exactly how long it takes to air up a tire. If you have them all at, for example, 7psi and you want to go back to 27, it might take 60 seconds per tire. So count to 60 and check with the gauge that's in your other hand. You can switch back and forth from the air hose to the gauge in 2 seconds. The 2nd-4th tires will take the same amount of time to fill. After a few trips, I got to the point where I could get within 2psi per tire using only the count-down method.

With the York, I found the most valuable thing to have was a hand throttle. Pin it at 2000rpm and it's a dream.

Also, 110-145 psi seems high. Aren't most air tools supposed to be regulated around 90psi? I had mine on at 90 off at 130, and most people I know do the same. I've run all my tools off it at one point or another. The only things it has no hope of keeping up with are the die grinder and paint sprayer.... :)
 
the regualtor is a fine idea, i think why you havent seen it done is cause its not worth the time. i tried the regulator and it didnt last the summer before it started leaking and hissing all the time,,, dust? i dont know. then i had an inline guage for a while and could see the air press in the tire while it was filling, but it too broke down in a short amount of time, dust? i dont know. like others have said it doesnt take long to re-inflate the old fashion way and thats just K.I.S.S. wich is good for me.

That's an excellent point, yes if you regulate it down you'll have less flow. I think the t'd blow-off valve is a better bet if you really want a safety mechanism, though the KISS principle seems to be more in the majority, for good reason.

I for one know all too well what it's like to spend a seemingly endless amount of time fiddling around with crap that I put there... while all the heathens & neaderthals in their rudimentary mod-free trucks enjoy an issue-free day.
