Run-flat tires are designed to allow you to continue driving for a limited distance at a reduced speed after a puncture or loss of tire pressure. The specific distance and speed you can drive on run-flat tires depend on several factors, including the tire manufacturer's specifications and the nature of the puncture or damage. Here are some general guidelines:

Typical Run-Flat Tire Specifications:

  1. Distance: Run-flat tires are typically rated to allow you to drive for about 50 miles (80 kilometers) after a puncture or loss of pressure.
  2. Speed: You can usually continue driving on run-flat tires at speeds up to about 50 mph (80 km/h), but this can vary by tire model and manufacturer.

Factors Affecting Run-Flat Tire Performance:

  • Extent of Damage: The ability to continue driving on run-flat tires depends on the severity and location of the puncture or damage. Large punctures or sidewall damage may limit the tire's ability to function as designed.
  • Tire Condition: The condition of the tire before the puncture (e.g., wear, age) can also impact its ability to safely run flat.
  • Driving Conditions: It's important to drive cautiously and avoid sudden maneuvers or high speeds when using run-flat tires, as they are intended for temporary use to get you to a safe location for repair or replacement.

Important Considerations:

  • Safety: Run-flat tires are designed to provide temporary mobility after a puncture, but they are not intended for prolonged use in a damaged condition. Continuing to drive on a damaged run-flat tire can compromise safety and further damage the tire.
  • Repair or Replacement: It's recommended to have a professional inspect the tire as soon as possible after running on a flat tire to assess whether it can be repaired or needs to be replaced.
  • Vehicle Compatibility: Some vehicles equipped with run-flat tires may have specific monitoring systems that alert you when a run-flat tire has been activated. Follow the vehicle manufacturer's guidelines for handling run-flat tire situations.
