How often should I change my tires on a car, and what factors should I consider when determining the ideal frequency for this essential maintenance task? Is it solely based on the number of miles driven, or do other elements play a role in tire longevity? For instance, could driving conditions, such as frequent exposure to rough terrains or inclement weather, significantly influence tire wear? Moreover, what about the variance in tire quality and design? Are certain tires inherently more durable, requiring less frequent replacement compared to others? In addition, how do driving habits, such as aggressive acceleration or frequent hard braking, impact tire lifespan? Should I also take into account the age of the tires, irrespective of their appearance or tread depth? Ultimately, how do I make an informed decision regarding tire changes to ensure optimal performance and safety while driving?
