How far can a run-flat tire go without air?

[SanDavid]

Run-flat tires can travel up to 80 kilometers without air. The maintenance methods for run-flat tires are: 1. Regularly clean stones from tire treads; 2. Minimize exposure to direct sunlight; 3. Promptly check tire pressure; 4. Pay attention to suspension maintenance; 5. Be mindful of driving habits. The functions of tires are: 1. Support the entire weight of the vehicle and bear the load; 2. Transmit traction and braking torque to ensure adhesion between the wheels and the road surface; 3. Reduce and absorb vibrations and impacts during driving, preventing excessive vibration and premature damage to vehicle components; 4. Adapt to high-speed performance and reduce driving noise, ensuring safety, handling stability, comfort, and fuel efficiency.
