The list includes 13 Performance Tires with the Best Treadwear Ratings, including the Toyo Extensa HP II, a high-performance all-season tire and one of two Toyo tires that could've made the list. The list also includes brands from Vredestein, Cooper Tires, and Tire Rack. The rankings were based on the Uniform Tire Quality Grade (UTQG) rating, which measures tires on several performance aspects, including longevity. The most recent addition to the list is the Cooper Cobra Instinct, which carries a rating of 500 UTQG and maintains this rating across all sizes and offers a 45,000-mile warranty. Despite not being widely recognized, the inclusion of Bridone's Bridgestone's tires on the list was a surprise.
