How should tires be stored when not in use?

Storing tires properly is essential to maintaining their integrity and prolonging their lifespan. The best practice is to keep tires in a cool, dry place and away from direct sunlight. This environment helps prevent the rubber from deteriorating, as exposure to heat and UV rays can cause cracking and hardening of the tires, making them unsafe for use. A dry location prevents moisture accumulation, which can lead to mold or corrosion.

In contrast, storing tires in a humid area with high temperatures, as suggested in one of the options, can accelerate tire degradation. Direct sunlight exposure can also damage the rubber, leading to issues like loss of elasticity and surface cracking. While keeping tires in a vehicle trunk may seem convenient, it can expose them to heat from the vehicle and could also lead to unnecessary wear if not stored properly.

Overall, the correct storage method emphasizes maintaining an optimal environment that shields tires from harmful conditions, ensuring they remain safe and effective when needed.
