What does the treadwear grade indicate?

The treadwear grade is an important aspect of tire specifications that provides information about the expected longevity of a tire. This grade is determined through standardized testing, focusing on the rate at which the tire wears compared to a reference tire. A higher treadwear grade indicates that a tire is expected to last longer before it needs to be replaced due to tread wear. This metric is particularly useful for consumers seeking tires that offer durability and value over time.

While load capacity, performance in wet conditions, and heat resistance are critical qualities to consider when selecting tires, they are rated based on different metrics and standards, not the treadwear grade. Therefore, understanding the treadwear grade specifically informs customers about how long they can expect the tread of their tire to last under normal driving conditions.
