it appears that I have another one. Fortunately this one shouldn’t be a hard one to fix and hopefully won’t cost that much money.
I’m fairly sure the tyre has an inner tube, but I think it may have been damaged around the valve as when I push the valve to the side. air starts leaking out.
Too late for attention today though. I shall have a look at it tomorrow assuming I can fight my way through Ingrid’s rain.
