You forgot date code...

You don't want old tires.

That's a good point.
Thanks for bringing that up.

There is a date code on every tire.
And a plant code and sort of serial number.

That date code doesn't work well for online tire buying.
But if you're in a tire store, you can hand select the latest dates.

Probably they'll not really want you doing that.
At Costco you might get away with hand picking by date code since they
store the tires right there in the store (AFAIK).
