Methods to check the size of car tires: The tire size is printed on the sidewall. For example, in 175/70R1477H, 175 represents the tire width of 175mm, 70 indicates the aspect ratio of the tire section is 70%, meaning the section height is 70% of the width, R stands for radial tire, the rim diameter is 14 inches, the load index is 77, and the speed rating is H. Tires are one of the most important components of a car, and their functions include: 1. Supporting the entire weight of the vehicle, bearing the load of the car, and transmitting forces and moments in other directions; 2. Ensuring good adhesion between the wheel and the road surface to improve the car's power, braking, and passability; 3. Preventing severe vibration and early damage to car components.
