There are no date codes on tires that old.
I worked at a Chevy store in the late '70s. The owner opened the lot right after WWII, so his first cars were 1947 models. He kept one of each year set aside and then stored them in a warehouse; then later in a climate-controlled building on the lot. He'd pick out a model and order it to his specs. Some years were Impalas, other years were Corvettes, a big-block Nova, a Cameo pickup, a Nomad, one of THE last Chevy caprice convertibles built. Whatever caught his eye as something he wanted, he ordered it. No "speculation" involved. There was a gorgeous '59 Impala four-door hardtop in the bunch, so it was not limited to 'Vettes or whatever in the collection. For 1979, he ordered a loaded Impala wagon, which was the first $10K+ Chevy (other than a Corvette) we'd ever seen!
He died in the late '80s, so I have no idea whatever became of the collection. He'd take one out for a drive now and then, but all but two had less than a hundred miles; and one had 3.1 miles on it. All brand-new cars and trucks with all of the pre-delivery tags and covers on them. Very cool collection.
