Another influencing factor is temperature. High heat can accelerate the aging process, while excessive cold can make rubber brittle. Areas with high ozone levels also pose a threat, as ozone can penetrate the tire surface, leading to cracking.

2. Material Deterioration:
Material deterioration refers to the natural breakdown of the tire’s components over time. Rubber compounds include various additives that can lose effectiveness as the tire ages. The American Society for Testing and Materials (ASTM) states that tires can begin to age and exhibit signs of deterioration after about six years, even if they have not been used extensively. For example, studies have shown that oxidation reactions can lead to the formation of cracks in the rubber as it ages. Additionally, tires that are too old may not provide adequate traction or support, which compromises safety on the road.

3. Lack of Maintenance:
Lack of maintenance plays a crucial role in the aging process of tires. Insufficient care, such as failing to check tire pressure regularly or neglecting to align and rotate tires, can accelerate wear. The National Highway Traffic Safety Administration (NHTSA) recommends checking tire pressure monthly, as improper inflation can lead to uneven wear and increase the likelihood of cracking. Regular inspections can catch signs of deterioration early, allowing for timely replacement before tires become hazardous. Cases have shown that drivers who actively maintain their tires significantly extend their life span and improve vehicle safety.

How Do Environmental Factors Contribute to Tire Deterioration?

Environmental factors significantly contribute to tire deterioration through exposure to heat, ultraviolet (UV) light, ozone, moisture, and road conditions. These factors can lead to tread wear, sidewall cracking, and overall structural degradation over time.
