Condition of the tyre - stored in cool, dry place, away from heat source and sunlight. Never been used before. Surface of tyre is ok, no scrubs. No crack, no oxidation, no hardening. At most just signs of storage over those years.

Any street or road tyres, any applicable discounts, or any other factor that you can think of.
Basically, the only thing wrong is the manufacturing date.
Bottom line, you would fit that tyre, and use it like normal.
