None of these suppliers (DLP, Wingstuff etc) have piles of tires sitting around for years, they are getting them in from the manufacturers to run these promotions etc, the manufacturer is sending them out as good to use, they may be a few years old and being sold cheap as they are aging them out.
They will of been stored as per the manufacturers specifications
You have to do what you think is right for you contact the maker and ask them when they released that batch and if they are good
