I know that many tire stores in AK, will not install tires that are 10 years or older on cars. Since we usually swap out studded for non-studded depending on the season, I have been in tire shops more than once and seen this occur to people. First I saw it occur at as Costco. I really didn't think about it, as I had always been accustomed to having replace tires about every 3-4 years minimum anyways,.
