"The letters and numbers on tires represent: production date, tire size, and specifications. Tires are an indispensable component of a vehicle and a crucial part of driving. The letters on tires serve as their identity card. Below is a detailed explanation: Production Date: There is always a DOT code on tires. The last four digits of this code indicate the production date of the tire. For example, if the last four digits are 1917, the last two digits of the combination represent the production year, which is 2017. The first two digits represent the production week, meaning the tire was produced in the 19th week. Therefore, the combination 1917 indicates that the tire was produced in May 2017. Tire Size and Specifications: Tires typically have a code like 205/60R1691V. Although the numbers and letters may vary, the format is similar. The meanings of this code are as follows: 205: Represents the tire width in millimeters (mm). 60: Represents the aspect ratio, which is the ratio of the tire's height to its width. A smaller number indicates a flatter tire. R: This letter indicates that the tire has a radial structure. Common types are R (radial tire) and D (bias tire). 16: This number indicates that the tire is suitable for a 16-inch rim. 91: Represents the maximum load capacity of a single tire, which is 615 kilograms. For four tires, the total is 2.4 tons. V: This letter indicates the maximum speed limit of the tire, which is 240 km/h."
