Is a Tire Wear Index of 280 Considered Low?
2 Answers
Theoretically, it depends on the "T"—Treadwear Index (wear values generally range between 160-540), and 280 is not considered low. Summer Standard Type: Tires with a wear index between 160-300 are classified as summer standard type. Summer High-Performance Type: Tires with a wear index between 160-200 are classified as summer high-performance type. All-Season Standard Type: Tires with a wear index between 300-540 are classified as all-season standard type. The higher the tire wear index, the more wear-resistant the tire is. However, higher is not always better, as when the wear index reaches a certain level, it may correspondingly lose some performance.
I drive long distances frequently, so I place great importance on tire wear resistance. A treadwear rating of 280 isn't considered low—the range is typically between 100 and 400, so 280 falls in the medium range. From my experience, tires with a 280 rating can last around 50,000 kilometers, not wearing out as quickly as those with ratings just over 200. Long-distance driving does cause more tire wear, but a 280-rated tire still offers decent grip, ensuring safety without being too slippery. Of course, if you often drive on rough roads or have an aggressive driving style, wear will accelerate, so I recommend regularly checking tread depth and tire pressure to extend their lifespan. Overall, a 280 rating suits most road conditions—no need to worry.
