All P-metric and LT tires sold on the market come with a DOT code. This is the tire manufacturer date code which is a 4-digit number. The first two numbers indicate the week, while the second two show the year of the manufacturing. Therefore, if the DOT code states 1221, it means the tire was manufactured on the 12th week of 2021.
