Let's start with the basics. Tires have a limited lifespan, and it's not just about the mileage. You see, tires are like the shoes of your car, and just like how you need to change your shoes every now and then, you need to change your tires too. But, how often is often enough?
Say you're an average driver, cruising around 12,000 to 15,000 miles per year. In that case, you should probably change your tires every 6 to 8 years, or when your tread gets too low. But, if you're a road warrior, driving much more than that, you might need to change them more frequently.
