The higher the treadwear rating, the greater the what?

The higher the treadwear rating signifies that the tire is designed to last longer before its tread wears down, which directly relates to increased mileage. Treadwear ratings are typically measured on a scale where higher numbers indicate better durability and a longer lifespan for the tire. This means that tires with a greater treadwear rating can handle more miles before requiring replacement, making them an economically sound choice for drivers looking for longevity in their tires.

In this context, while traction and performance during curves are important factors in tire selection, they are not directly linked to the treadwear rating. A tire could have a high treadwear rating but still offer variable performance depending on its design and rubber composition. Additionally, the risk of tire blowouts is more contingent on tire maintenance, inflation, and environmental factors rather than the treadwear rating itself. Thus, the key takeaway is that a higher treadwear rating correlates with increased mileage potential.
