Yesterday I discovered a flat tire on a grain trailer, not sure what that is about as I inflated it and never lost air over night for whatever that can tell, seem to have a theme of that on that trailer every spring Anyway I thought I may as well check over all the tires on the truck and trailer and I should add that I have those flow through internal sealing type caps which I know some tire shops want to blame for every flat tire one brings into their shop if they see that cap. However its a complete pain in the ass to access the valve caps on these wheels, the trailer has the steel wheels with the many small holes style wheel so certainly can't reach through them and they are also impossible to reach between the duals. The newer Lode King came from the factory with those style caps and for sure its a lot easier to check and add air vs dealing with caps,that's why I added them to this trailer. So I was having an issue with one tire not being able to take any air, I could check the pressure but could not hardly add air and figured maybe there is something wrong with that special cap. So I take the cap off ( I have a special tire tool to reach through and take caps off on the inside dual, it sort of works on these caps ) and when I took that cap off the air was flying out of the valve core in the stem. I did not have a valve removal tool other than the little cross style one that has the thread chaser etc on it so to town today to get something, wasn't really what I wanted as its barely long enough but would be a typical core removal tool as I didn't feel like removing the tires just to access the core if I did not have to. So I take the core out and I found something interesting, mechanical damage on the valve core. I probably had that tire off to get a repair done on it within the last few years ago and somehow the core held when they installed it into the stem and then my flow through/sealing cap I installed after I got home held the air when the core finally did not. It would be hard to take a photo of the core without an extreme macro camera setting but what I saw is that the little brass cup if you will that has the rubber sealing ring it in, the cup was bent on the edge so therefore deformed and the bent edge was catching the mating sealing surface of the valve preventing it from sealing. There is no way an object inside the tire could go up the stem and cause damage like this, I suspect that when they inflated the tire at the tire shop they inflate with the core out so it can flow in fast ... then they "slam" in the core as the air is rushing out and I can see how the delicate sealing cup could get smacked up against the inside edge of the hollow stem as they fight to get the core in. That's my theory anyway, unless the core was damaged by some other method in their shop, stepped on it etc. Probably at first the sealing ring would stand out more proud and seal and then compress over time. That valve core does not cost much but is rather important that it works !.
Has anyone else on here used those flow through caps ?, these are not the true extensions, just a cap that is long enough to have the sealing system inside of it and the center poppet that the tire gauge or inflator will press and in turn press the valve core stem to add or bleed air.

We had those on one truck and they always leaked. Got rid of them and tires stopped going low. We use the steel caps with the hex on them. Use a 3/8 socket on an extension with the driver handle and can reach threw the small holes on the aluminum tires to remove the caps and put then back on. Made a couple tools to keep in the trucks to take caps off if needed to add air when we are away from home.

I would not say I could nail down a leaking issue to these units although its always in the back of my mind, each time there was a leak it turned out to be something in a tire but I do realize there is an added risk to using them over the proper type of cap that has a sealing ring in it. However I don't use them on the steer axle of trucks and one of the trucks I am doing exactly like you mentioned with long 1/4 extension and hex caps which I find not always so easy to source. The long stem extensions which I have never used and would be only used for the inner dual, they are from what I understand far worse of a risk for mechanical damage, driving through mud or rocks hitting them since they stick out across the gap between the duals. For better or worse that tire with the messed up core, it was not really much lower than anything else and it had been holding the pressure itself since the core wasn't doing anything.

Flow through caps... are you talking about the crossfire deal that connects the two valve stems?

That is one thing I like about mb safeties. I don’t have to recheck tire pressure on duals . I hate that job , especially if the valve stem is pushed up against the tire rim. Norther farmer , I was hoping you were going to say the newer style valve stems cured all problems .

Flow through caps... are you talking about the crossfire deal that connects the two valve stems? No, these don't connect the tires together with hoses like your thinking of, all these do is take the place of a valve stem cap and have an internal seal so air can only come out of the outer end if the center portion is pressed in. There is a shaft inside that moves to depress the actual tire stem core tit to allow air in or out of the tire. With those hose arrangements, whatever I have been around to see such as when my dad had a motorhome, the tire can't have any core in the valve stem and with the ones he had the tires were not connected, each tire of a dual set had its own hose and then a bracket where the two hose ends terminated where it was easy to get the caps off of them and in that end of each hose their was a valve core. It did work for sure but again not meant to be running that contraption in mud or on gravel roads if one can help it as I could see things going sideways. Here is a link to a photo of the the flow through cap, I would say its a little over double the length of a normal valve stem cap.

Norther farmer , I was hoping you were going to say the newer style valve stems cured all problems . As you can see I do not like the job either !, and after getting the one trailer that had these flow through units on from the factory I experimented with the other trailer and one truck. As you can see the discussion, they are not exactly the 100% trust worthy solution but they certainly do allow for much easier checking of tire pressures which in theory means gets checked more often. As to a valve stem pushed up against the tire rim, if you are speaking of hub piloted wheels where the tire is tubeless and the stem is bolted into the wheel, you either had the wrong style stem bolted in or its bent to shit ... that's my thought anyway. With a mess like that, there is no good way to check tire pressures and either the stem has to be straightened if it can be or replaced. Now the older dayton wheels with a tube type tire, they are a real joy due to stems that like to flatten themselves against the wheel depending on the style of stem that came with the tube. Honestly the best wheels to access the valve stem are those steel wheels with the two big holes in each wheel and align the stems opposite when putting the wheels on, however I don't own anything with that style wheel.
A neighbour owns two grain trailers that have the self inflation system for the tires, I've never looked at how they work but that is one way of not having to check your tire pressures, buy a new trailer with self inflation !

Self inflation works until you don’t shut the valve and you’re gone for a week or two and come back to all the tires flat.

He had just gotten the trailer when I had asked him about the system and he knew nothing then and that was like two years ago, I am sure he has figured out since. Have not driven past his yard and seen the trailer sitting on the rims, not yet anyway.

Newer ones maybe fixed that problem. Perhaps it can only fill the tire not let the air out. I know guys who tan the tire boss system on their vac trucks and would have trouble every so often.

Well daily life is sure different in Dubai My sister says most people in dubia don’t drive to a gas station ! Instead most people have an APP and than a truck comes and fills your car either at your parking lot or your driveway. I asked my sister out of curiosity what the price of gas is in the Middle East city. I was shocked she didn’t know and told me how she gets her suv filled ! Can you see that service here in North America ?

Ended up being a lot less of a rodeo than I thought.

Well this morning I think it's fair to say I almost killed myself in a shaving accident, and not likely in the way you would think. I was lathered up with shaving cream and partly done when I had a cough followed by a hiccup, at least that's what I think happened... I must have had a little extra cream around my mouth and got some down my windpipe on the inhale. I then coughed to try and get as much out as I could and then realized I could not inhale! So for what seemed like eternity(probably around a minute) I rinsed my mouth out and tried to inhale, because I was in front of the mirror it was obvious I was getting pretty red and my eyes were bulged out. Finally I was able to get a little inhale and slowly a little more, right about the time my wife prayed for me actually. I thought I was gonna die because I'd already lasted longer than I probably could hold my breath for if I tried, I'm sure it was stressful for the wife and kids to see. So looking at the ingredients in shaving cream I don't know what nasty chemical in particular caused my windpipe to close like that, I have no asthma or allergies at all. My advice would be to make sure you NEVER get a mouthful of shaving cream. Later today I bough the parts to refurbish my electric razor. And it rained today, that was kinda nice. 8-)

WOW! What a way to go. That definitely would have made it on the top ten list of weirdest ways to have died. Now I'll be thinking of this every time I shave. Who knows how many lives you will have saved.👍

I have never heard of anything like that. Glad you're ok.
