Tire specifications

Tire specifications

Tire specifications are often represented by a set of numbers. The first number indicates the tire section width, and the latter number indicates the rim diameter in inches. For example, 165/70R14 means a radial tire with a tire width of 165 mm, a flatness ratio of 70, and a rim diameter of 14 inches. Some tires also contain other letters or symbols, which have special meanings: "X" represents high-pressure tires; "C" represents reinforced tires; "B" represents bias tires; "1" represents low-pressure tires.
