Help with getting air into strange tyre valves!

Does anyone know how to get air into these inner tube valves on my commando please!

Uh......unscrew the valve cap and, voila, add air at the traditional air valve in the time honored way.

You turn that cap round 180 degrees and the nib on the top allows you to unscrew the valve out, one less tool in the tool kit.

Also, steel valve caps with an integral o-ring do not deflate at high speed like the rubber caps can. The centrifugal force allows the inner part to oscillate and lose pressure. Not a problem under 200mph

In some countries metal caps has to be used on road race bikes. Love those. Not very common today. Every now and then goes to the local tyre shop and search in the valve cap bin for discarded ones. Have at least one on each bike.
By the way, do you too has the nut a bit loose? In order to easily see if the tyre has slipped on the rim. As long as the valve points at wheel centre it has not slipped.
A bit off topic, back when I raced speedway, we cut a hole on the right side of the rear tyre for the valve. Not to rip valve off the inner tube when tyre slipped on the rim. No problem when only turning left.

I'd have killed for one of those a few weeks back!! Just topped up both tyres a couple of pounds, pulled the pump off the front tyre and listened to it deflate to nothing !!
Searched high and low for an old tube that I knew had a similar cap, AND the redundant pencil type gauge that had the tool screwed in the end. Both permanently AWOL, of course.
Ebay to the rescue, did give it a tweak with needle nose pliers but thought it prudent to get the right tool down there before I risked life and limb on it.

I could be mean, but I'll resist

We start calling you just Gene, then????

Oh dear how embarrasing.....thx all! I thought if I unscrewed that top piece all the air would come out the tyre the same as the valves on my mountin bike

somehow this is an age related thing....

Ah meh....

This must be the start of the decline of man.

Come on guys , we missed the chance----first reply should have been : you need to get down on you knees , wrap your lips around it tightly and blow for all you're worth. Just kidding of course. When I was active duty in the Navy we used to play jokes on the new guys. It was harmless for the most part, now it's called hazing & a huge no no in todays politically correct world of thin skinned kids. Just things like sending the new guy into maintenance control for the "key" to the jet or aircraft so we could move it. Or sending them out with a plastic trash bag to collect an APU exhaust sample. Taping a guy to a chair can get carried away, same with setting their boots on fire if they've fallen asleep (hand sanitizer light for a minute, don't cha know along with various other cleaning compounds/solvents etc...Or telling them to speak into the urination tube in the cockpit , so the guy outside can hear them, like saying "brakes off, ready to move it". Of course not everybody fell for some of the pranks, or reacted to or dealt with them the same way, but it sort of gave you an idea of who's who. Now that I see this in print , perhaps it would have been better to bite my tongue. All joking aside Pete, this is definitely the place to ask questions.

I could see how those valve caps could be mistaken for Presta valves which are common on bicycles.

Lacking knowledge is no sin.

I have the same steel caps which normally have a small black plastic cap on that cap.
As I rule I roll the bike until the valve is at the spot that needs air.

In fact it can be a prerequisite for it.

Agreed, but folks need guidance sometimes to learn when encountering unfamiliar things. I find no fault on OP's part so I cannot make light of the query...... Now he knows. My own ignorance, to my chagrin, knows no bounds at times. I even pull my head out every now and then accompanied by a most resounding loud popping noise ready to listen and learn... This reminds me of needing to ride my beastie tomorrow if there's no rain. May the snort be with you guys.

A tire valve stem cap is an interesting starting point to begin the learning about the Commando, but it beats replacing the horn.
