Went to inflate tyres at the weekend. Front tyre wouldn’t inflate.

Removed dust cap. Unscrewed top nut of presta valve. Depressed top of valve to release a bit of what little air was in there. Clamped pump head in place. Pumped – only to meet a lot of resistance. Removed pump head, depressed valve, tried again – same resistance. Unscrewed and removed the valve core, put it back in, tried again. Still won’t accept air. Pump is working fine on other tyres / tubes.

I have had this occasionally in the past, but usually some form of the above resolves it. Any suggestions?

Is it set up tubeless? I sometimes have to clear out sealant clogs.

If not, can you get air in with the valve out? It should be very easy. If you can, try replacing the core.
