how far can run flat tires go

The distance a vehicle can run on flat tires depends on several factors, including the type of tire, vehicle speed, road surface, and whether the tire is completely flat or just partially deflated. Here’s a general breakdown:

  1. Completely Flat Tires:

    • Short Distance (Emergency Only): You should not drive on a completely flat tire for more than a very short distance (less than a mile) and at a very slow speed (under 20-30 mph). Driving farther can damage the tire, wheel, and potentially other components like brakes and suspension.
    • Run-Flat Tires: Some vehicles are equipped with run-flat tires, which are designed to allow you to continue driving for a limited distance (usually up to 50 miles) and at moderate speeds (up to 50 mph) after a puncture. Check your vehicle’s specifications for exact limits.

  2. Partially Deflated Tires (Underinflated):

    • If a tire is only partially deflated, you may be able to drive carefully to a repair shop, but handling and safety will be compromised. It’s best to avoid high speeds and long distances.

  3. Risks of Driving on Flat Tires:

    • Further damage to the tire (making it irreparable).
    • Damage to the wheel rim.
    • Reduced braking and steering control, increasing the risk of an accident.
    • Potential damage to suspension and braking systems.

If you experience a flat tire, it’s best to safely pull over as soon as possible and replace it with a spare or call for roadside assistance. Always refer to your vehicle’s owner’s manual for specific guidance.
