Always read the last four digits of the DOT stamp on your Nexen tires. That small code is your best defense against age-related tire failure. When in doubt, have a professional tire technician inspect your tires and confirm the date code for you.

Tires are the only part of your vehicle that contacts the road, making their age a critical safety factor—regardless of tread depth. For Nexen Tire owners, decoding the manufacturing date is straightforward once you understand the U.S. Department of Transportation (DOT) code stamped on every sidewall. Where to Find the Code Look for an oval-shaped stamp that begins with the letters "DOT." On Nexen tires, this is typically located on the lower sidewall, just above the bead (where the tire meets the wheel rim). You may need to turn your steering wheel fully to one side or crawl under the vehicle for a clear view.
