Fremont Motors is taking some of the guesswork out of determining how much longer your vehicle's tires will last by exploring the topic of tread depth on its website.

Tread depth is measured in 32nds of an inch, with new tires typically having 10/32 of an inch of tread, the posting said. Truck and SUV tires or specialty tires may have deeper tread depth. The U.S. Department of Transportation (DOT) recommends replacing tires that have 2/32 of an inch or less of tread left. In states such as Wyoming, vehicles are required to have 4/32 of an inch left.

To figure out how much tread is left, turn a penny so Lincoln's head faces the tire. Stick the penny between two treads; if Lincoln's head is partially covered by the tire, the tire has more than 2/32 inch of tread left, the posting said. If the entire head is visible, it's time for new tires. Do the tread test in several areas on the tire, as tires may wear unevenly.
