Why Is It Important to Store Tires Properly to Avoid Cracking?

Storing tires properly is crucial to avoid cracking. Proper storage helps maintain the integrity of the rubber and extends the life of the tires.

According to the Tire and Rubber Association of Canada, rubber degrades over time due to exposure to various environmental factors, making proper storage essential for preserving tire quality and performance.

Tire cracking occurs due to several factors. First, rubber compounds in tires can lose elasticity over time. This loss can be exacerbated by environmental exposure, which can include sunlight, heat, moisture, and oxygen. Second, improper storage can lead to physical distortions in the tire shape, which may contribute to further cracking. Third, tires may also suffer from a decrease in performance characteristics, such as traction and flexibility, when not stored correctly.

Key technical terms include “ozone cracking” and “UV degradation.” Ozone cracking refers to the small cracks that can form in rubber materials when they are exposed to ozone in the atmosphere. UV degradation is the breakdown of materials due to prolonged exposure to ultraviolet (UV) light, which can weaken rubber compounds.

The mechanisms behind tire cracking involve a complex interplay of chemical reactions. Over time, oxygen and ozone cause the rubber to oxidize, which results in the formation of cracks. Prolonged exposure to high temperatures accelerates this reaction. Additionally, when tires are stored improperly—for instance, stacked vertically rather than stored flat—they may develop flat spots. These flat spots can lead to uneven stress on the tire and increase the likelihood of cracking.

Specific conditions that contribute to tire cracking include exposure to sunlight and heat. For example, leaving tires in direct sunlight or in a hot garage can significantly shorten their lifespan. Another condition is the presence of contaminants, such as oil or chemicals, which can further deteriorate the rubber. Storing tires in a cool, dark, and dry environment, away from direct sunlight and heavy loads, can help mitigate these issues.
