Treadwear number

**Treadwear Number**

The treadwear number is a standardized rating used to indicate the expected durability and lifespan of a tire’s tread. It is part of the Uniform Tire Quality Grading (UTQG) system developed by the U.S. National Highway Traffic Safety Administration (NHTSA). A higher treadwear number generally signifies a longer-lasting tire, meaning it should resist wear better over time compared to tires with lower treadwear ratings. This number helps consumers compare tire longevity when choosing the best option for their vehicle and driving needs. Keep in mind that actual tire life may vary based on driving habits, road conditions, and maintenance.
