I’ve just bought 4 new winter tyres for my car. How should I store them?

Question from visitor, 08/01/2010 :I’ve just bought 4 new winter tyres for my car. How should I store them? Is there anything in particular I should do if they are already mounted on the rims?
Answer by rezulteo, 08/01/2010 :

Stand the tyres upright when they are not on the rims and stack them flat if they are mounted on the rims. They should be stocked in a dry well ventilated area and kept out of the light.
