How can you tell the expiry date of a vehicle tire?

You can determine the expiry date of a vehicle tire by checking the DOT (Department of Transportation) code printed on the sidewall of the tire. The last four digits of this code indicate the week and year the tire was manufactured; for example, "2319" means the 23rd week of 2019. Generally, tires should be replaced after six years, regardless of tread wear, and many manufacturers recommend not using tires older than ten years. Regular inspections for signs of wear or damage are also essential for safety.
