Question

1. the letter at the beginning of a tire code represents:

tire size
tire type/class
tire width
tire construction

Explanation:

In tire coding, the first letter (e.g., "P" for passenger, "LT" for light truck) indicates the tire's type or class, defining its intended use and vehicle compatibility. Tire size, width, or construction are represented by other parts of the tire code, not the initial letter.

Answer:

Tire Type/Class
