Avon Update,
As mentioned Cooper tyres owned Avon who were then bought out by Goodyear, Avon factory closed at end of 2023 and production was moved over to France ( same factory as Dunlop tyres) they have eventually started to produce our size tyres at long last, I can confirm this as I spoke with my local supplier within the last week who ordered me a rear, I called in to the store to check the manufacturers date stamp...6/25, so February 2025 it is.
He told me Goodyear had informed him production was going to be at end of this year as even their stock states 'out of stock' I rang another dealer who confirmed he could get one as well. So they are coming through....slowly.
I can only speak from the UK side of things
