Hello… have two ways to store my tires. Maybe someone can help me find the better place to keep the tires as long as possible. The ideal place to store is, to my knowledge, dry, cool and dark. I have a low cellar that is relatively humid. Have measured the following today: 11° C and 70% rel. Humidity. Are 70% humidity too high to store here tyres? Does the moisture damage the rubber or can only rust the rims? Are 70% In addition, I have a small plank in the open air in a parking lot. Here the tires could lie without direct sunlight, but not completely in the dark, because between the planks on the walls there is approx. 2 cm air. In addition, in the case of rain, spray water can enter through the cracks. And here the tires would be exposed to temperature fluctuations. Which place do you think is suitable for the tires?
