What action is required for fleet vehicles after a tire reaches the age of 7 years?

When a tire reaches the age of 7 years, it is critical to replace the tire, regardless of its tread depth or apparent condition. This recommendation is based on the understanding that tires deteriorate over time due to factors such as exposure to heat, sunlight, and environmental conditions, which can compromise their structural integrity.

Even if a tire appears to be in good condition externally, the rubber compounds can harden and lose elasticity as they age, increasing the risk of tire failure during operation. Fleet management protocols prioritize safety and reliability, which necessitate the replacement of tires that have reached this age threshold to minimize risks related to blowouts or other issues while the vehicle is in service.

In contrast, actions like rotating, repairing, or merely inspecting tires do not address the fundamental safety concerns associated with aged tires. These tasks may be part of regular maintenance, but they do not mitigate the risks posed by tires that are beyond their optimal lifespan. Therefore, replacing tires after 7 years of service is a proactive measure aimed at ensuring the safety of drivers and passengers.
