Real world pre-fitment shelf life is closer to 2 or 3 years - especially if you NEED it to perform well once fitted. Also depends how it's stored.
Do you have anything on paper about this 2-3 years time frame?
I don't, I have worked with tire experts several times over the years on legal cases and was just parroting what I have been told.
