Tire specifications are commonly represented by a set of numbers, with the first number indicating the tire section width and the latter indicating the rim diameter, measured in inches. 2. Some tires also include other letters or symbols with special meanings: "X" denotes high-pressure tires; "C" denotes reinforced tires; "B" denotes bias-ply tires; "-" denotes low-pressure tires. M and S are abbreviations for Mud and Snow in English, indicating that these tires are suitable for use on snowy and muddy roads. 3.
