Tyre valve adapters

[Dante6686]

Hi all

This time when trying to inflate the tires on my CBR600FM I told myself I've had enough of bending the valve stems so much, that you can see the cracks developing, to inflate my tires. So i bought a pair of the 45degree valve adapters, making it accessible for the air hoses on the petrol stations.

The only thing is I've never seen anyone use them and I don't know if it's safe to always keep them screwed on the valve during riding, or, will the centrifugal force of the wheel spinning or air resistance at higher speeds be able to snap/tear the valve off? (which obviously would be really, really bad on a dual carriageway.) Anyone ever used them? Any feedback much appreciated, Thank you.

I'd screw them on as and when. Then next time you have a tyre fitted, get them to put in valves with the angle built-in (they should be changing the valves each time anyway but most of them cheap out on you).

You might need to supply the angled ones yourself.

Search for "angled tubeless valves"

They fit them as standard to some speed triples so they are obviously good for the speed.

I cheap out on myself then because I change the tyres myself and never minded the valves - they might still be stock for all I know But it's a great idea, next time I change tyres i'll fit the angled valves, Thanks.

Leaving them on can cause a bit of imbalance of the wheel if you whip it on fast enough.
And +1 on the cheaters.
I usually ask them if they change the valves. They don't cost that much for standard wheels.
Last pair I had fitted to my thou had a broken seal on the rear valve. The previous fitters never swapped the valve.

Good point - didn't think about it. These brass adapters have considerable weight - probably heavier than a counter weight stuck on my front wheel last time it was balanced, thanks

Yeah, they can be inaccurate - I stick to one air compressor at a station close to my place to know what I can expect and then check with my gauge. To be honest, differences like one or two PSI don't bother me

I have angles valves as standard on my Trophy. They really make life a lot easier.

or you can buy air compressor with screw stem connector

Tyre valves aren't particularly strong, they are not designed to have extra weight hanging off them.
Leaving the extension on could cause premature and/or catastrophic failure, seems a big risk to take instead of just taking it off after use.

Don't leave them permanently attached. Mine lives under the seat in my tool kit and only comes out when required.

Hi

Used them many years ago on the FZ750 (16" wheel with twin disks made getting at the valve a pain). Left it on all the time. No issue with balance. But the tyre valve split, leading to an almost instantly flat front tyre (which was fun as I was doing about 65mph, just touching the brakes for a 40 limit that started with a bend, with a pillion).

All the best

Alternatively these are pretty handy.

(Michelin tyre valve extension on Amazon.)

Well made, easy to fit, good access, little stress on the valve and then you remove before riding.

Oh, and hello, this is my first post. There seems to be nowhere to introduce myself so I'll just dive in.

I have seen these used by quite a few people who own bikes with limited access so as to be able to adjust their tyre pressures

I have a 90 degree adapter that I keep in my pocket for those occasions when I might need it or when I see other people struggling to get air into their bike tyres.

But,as has been said,rubber tyre valves can become damaged,as has happened to me in the past year

I am not sure what happened to the valve rubber but I did see the situation in plenty of time and replaced it before it was too late
