I'm the same way.
If it's on the shelf for 10 years, I'll take it if you sell it for less then than a 2 year old tire.
If they cost the same, why would I not get the newer one.
Tires age, even with no use. Being kept inside in a controlled environment slows down the process, but it's still a process.
Nevermind the fact that a 10 year old new tire cost much less to make then. Why rip me on that tire for the same price as a 2 year old one?
