When you try to pump up the tyre, is the valve fully unscrewed, or is your pump one of those that needs to be locked on to the valve before it will let air into the tyre? If your valve core is indeed blocked, do you use tyre sealant? Sealant means that valve cores are more likely to become blocked. This video shows the symptoms, how to remove the core, clean it and replace. https://www.youtube.com/watch?v=uZBhSskQOPE Hope that helps. As for what you do about the valve core before tomorrow's that is up to you. Does the valve let air out all the time even when screwed down fully, or only when you depress the valve? If the latter, then I would think it should be safe for tomorrow provided the valve is shut down and covered with a dust cap. Good luck with whatever you decide.

AndyS Jul 2022 2:57pm, 2 Jul 2022 1,393 posts	0 AndyS My wife eventually managed to get the tyre off. Unfortunately, it was while I wasn't watching, so I still don't know what I was doing wrong. Replaced the tube. Rode to parkrun and back this morning - and picked up another puncture. It's almost like my bike is trying to tell me something...

Flatlander Jul 2022 3:26pm, 2 Jul 2022 2,520 posts	0 Flatlander AndyS What Ttontt says. It sounds like you need puncture proof tyres such as wiggle.co.uk In my use I have never had a puncture with them. Other makes are available, but be careful of those that claim to be puncture resistant - "resistant" just means they are less likely to puncture, whereas puncture proof means that there is an extremely small chance of puncturing (rough figures - 1 in 100,000+ miles instead of 1 in 500 - 1,000 miles for unprotected tyres). One can still get a puncture with a puncture proof tyre, but will be due to other things - 1. not removing glass/sharp objects from your tyre so that they eventually wear their way through the protective layer, 2. something penetrating the unprotected side wall (highly unlikely). 3. internal rim tape not properly seated, rough edges, valve gap not positioned correctly over the rim hole, 4. roughness of the wheel rim, 5. incorrectly tensioned spoke, the inside end will rub the inner tube, 6. faulty inner tube, valve etc.
AndyS Jul 2022 3:40pm, 2 Jul 2022 1,394 posts	0 AndyS The first one wasn't a puncture in the tyre - it was a pinch flat, so I'm not sure puncture proof tyres would help. Not sure about today's, as I haven't summoned up enough resilience to fight with it yet.
