You should not have any issue with these tires due to 2016 production date. The only brand I would worry about would be either Michelin or BFGoodrich. I have seen Michelin Premier A/S with stickers still on them with severe dry rot along the shoulder of the tire. The myth that tires expire due to age is generally not true. I am the inventory manager of a large used tire warehouse and have a great deal of experience with this subject.
No idea if these are rebate eligible. I just saw the deal and wanted to share. Worst they can say is no.
