FWIW now is the time for winter tire and wheel bargains. Lots of people sold a car and have them sitting around.
Be sure and measure tread depth. Lots of people seem to sell winter tires after a couple of seasons. They look good but the tread depth is well under the 10-12/32nd of new passenger tires and 14-15/32nd of light truck tires.
Unless they are really old or don’t look ok, I don’t worry so much about manufacture date. If they are kept out of UV they seem to hold up for a long time.
