- Overall Diameter: The diameter of an inflated tire at the outermost surface of the tread.
- Maximum Load Capacity: The maximum weight a tire is designed to carry under standard use conditions.
- Load Identification: Load Range with a letter (A, B, C, etc.). Standard Load and Extra Load are used to identify a given size tire with its load and inflation limits, when used in a specific type of service.
