How Does Tire Aging Contribute to Its Cracking?

Tire aging contributes to its cracking primarily due to the chemical and physical changes that occur over time. As tires age, the rubber compounds within them begin to degrade. This degradation results from exposure to environmental factors such as sunlight, ozone, and temperature fluctuations. These elements cause the rubber to lose its elasticity, making it stiff and brittle.

In addition, the loss of oils within the rubber contributes to its drying out. When the rubber dries, it becomes susceptible to cracking. Cracks tend to form in areas with high stress, such as the sidewalls or tread. Aging also weakens the tire’s structure. This weakens makes the tire less resistant to impacts and further exacerbates cracking under normal use.

Additionally, tires that experience poor maintenance or improper inflation may age faster. Under-inflated tires generate more heat, which accelerates the aging process. Properly maintaining tire pressure and performing regular inspections can help mitigate these effects. Thus, tire aging, combined with environmental factors and maintenance practices, significantly increases the likelihood of cracking.
