Does anyone know where I can get a 300 x 20 Avon Speedmaster ribbed tyre?
Unfortunately I believe these tyres have been discontinued, I cannot find any replacements on the internet. Best of luck!
Unfortunately the 20 inch tyres are very rare these days. You could visit the dustiest motorcycle shop in your area, he might have one tucked away in the attic... But even if he does, it might be perished and past its' sell by date.
Thank you for your replies.
It seems that Avon closed their factory at the end of last year, but will eventually start making Classic tyres in one of their overseas factories. Ensign tyres seem to be difficult to get hold of as well.
