Age of "new" tires

Just something to consider. If the car sits outside in the sun, and high temps (like here in Florida) I would not buy a tire that was not current year. No matter how many miles a year I put on them. If the vehicle sits in a garage, out of the sun, when not being used, You can get away with older date code.
I bought a late model used car a few years, ago. After dealer and I got done haggeling on the price, and had a deal, I hit them up for a new set of tires. The ones on the car were 9 years old (on the car when it was sold new). They put on a set that was between 2 and 3 years old. I told them "not good enough", I want not more them one year old. They did comply.
PS: You can't compare todays tires to the tires that were made 20-30 years ago. The rubber compound is totally different. I have two sets of M&H slicks that are identical. One set was made more then 20 years ago. The other set about 6 years ago. The sidewalls on the older tires look better then the newer tires. I think the tires from "way back" have more "NATURAL" rubber, in them.
