Automobile tires are measured in millimeters, indicating the section width and aspect ratio percentage. Below are the functions of car tires and precautions for their use: Functions of car tires: Support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions; prevent automotive components from suffering severe vibrations and early damage, adapt to the high-speed performance of the vehicle and reduce driving noise, ensuring driving safety, handling stability, comfort, and energy-saving economy. Precautions for using car tires: Owners should promptly remove foreign objects from the tires to prevent stubborn stones from getting stuck in the tread. When the tire wears to a certain extent, these objects can puncture the tire body, leading to air leakage or even a blowout. Rotate the tire positions every 10,000 kilometers to evenly distribute tire fatigue and prevent uneven wear, thereby extending tire life.
