The Penny Test. In the United States, tire tread depth is measured in 32nds of an inch. New tires typically come with 10/32â or 11/32â tread depths, and some truck, SUV and winter tires may have deeper tread depths than other models. The U.S. Department of Transportation recommends replacing tires when they reach 2/32â, and many states legally require tires to be replaced at this depth.
As an example of different tire diameters resulting from tires worn to different tread depths, we compared two 225/45R17-sized tires, a new tire with its original tread depth of 10/32-inch and a second tire worn to 8/32-inch of remaining tread depth.
