Car Tyre Not Pumping Up

I have gone to a petrol station to pump up my car tyre. When I add the air nozzle to my tyre, it doesn’t make that ‘sssssss’ sound, in fact there is no sound at all.

When I add the air nozzle to all my other car tyres, the ‘sssssss’ sound is there and thus, my tyres get inflated.

I have no idea why my car tyre isnt accepting the air, or what has happened to the nozzle on the tyre itself. To me it looks fine, but I’m no expert…..?

Any ideas on this?
