Environmental factors, such as sunlight and extreme temperatures, affect the rubber’s integrity. Additionally, a tire’s age contributes to its susceptibility to cracking. Incorrect air pressure can lead to sidewall stress. Physical impacts, like hitting a pothole, may cause cracks. Chemical exposure from road salt and oils also damages tires.
1. Environmental Factors:
Environmental factors lead to cracks in the tire’s sidewalls over time. Sunlight, or ultraviolet (UV) rays, can deteriorate the rubber material, causing it to become brittle. Temperatures freezing below 32°F and exceeding 100°F can also exacerbate this degradation, leading to premature cracking (American Tire Distributors, 2019). Tires regularly exposed to outdoor elements tend to develop cracks more rapidly than stored ones.
2. Age of the Tire:
Age affects the rubber’s elasticity and durability, resulting in cracked sidewalls. Rubber compounds lose their effectiveness after several years, regardless of tread wear. The Tire Industry Association states that tires older than six years should be inspected closely for damage. Studies indicate that tires can start to crack significantly after reaching their sixth year of use, even if they have not been heavily used.
3. Incorrect Air Pressure:
Incorrect air pressure affects tire performance and integrity. Over-inflated tires result in increased sidewall stress, which can cause cracks. Meanwhile, under-inflated tires can lead to excessive flexing, causing heat buildup and further damage. The National Highway Traffic Safety Administration (NHTSA) emphasizes that drivers should maintain their tire pressure according to vehicle manufacturer recommendations.
4. Physical Damage:
Physical damage contributes significantly to cracks in the sidewalls. Impact from potholes, sharp objects, or road debris can cause cuts and fractures. This type of damage often goes unnoticed until cracks appear. According to a study published by the Rubber Manufacturer’s Association (2018), around 50% of tire failures are linked to physical damage not detected during routine inspections.
5. Chemical Exposure:
Chemical exposure accelerates rubber deterioration and leads to cracks. Substances like oil, gasoline, and road salt can degrade rubber compounds. Tires are particularly vulnerable when subjected to harsh winter conditions, where road salt is prevalent. A report by the American Chemical Society (2020) highlights that ongoing chemical exposure may shorten the lifespan of tires significantly.
In conclusion, cracked sidewalls can pose significant safety risks and should be taken seriously. Regular inspection and maintenance can help mitigate these risks. Proper tire care can prolong tire life and enhance vehicle safety.
Why Are Cracked Sidewalls on Tires a Safety Concern?

Second, improper tire inflation can cause excessive stress on the sidewalls. Third, physical damage from potholes or curbs can also initiate cracks. Collectively, these factors reduce the tire’s lifespan and safety.
Rubber aging is a technical term that refers to the natural deterioration of rubber compounds over time. This process can lead to cracking. The ultraviolet (UV) rays from the sun can cause the rubber to harden and lose flexibility. Additionally, ozone exposure, often from electrical equipment, can accelerate this aging.
The mechanisms behind cracked sidewalls include the breakdown of the rubber’s chemical structure. This breakdown occurs at a molecular level, where ozone and other environmental factors weaken the rubber’s elasticity. When the tire inflates, the internal pressure pushes against weak points, leading to visible cracks.
Specific actions and conditions that contribute to tire sidewall issues include neglecting regular tire maintenance. For instance, failing to check tire pressure regularly can lead to overinflation or underinflation. Driving on rough or uneven surfaces can subject tires to stress, while storing tires in direct sunlight can increase the risk of rubber degradation.
