Agreed. Many factors. No only exposure to UV there is air pollution and ultimately heat cycles.
Little used and stored indoors??? 5 year rule would seem much too soon. Getting toward 10? Yep time to pause.
I have a set of 15 year old Michelin Xs I took of my Triumph. Were disintegrating before my eyes. Black stuff all over the side of car under hard driving. Scary. Replaced with Vredesteins. But still have them in case I ever enter that concours that will never happen!
