how far can run flats go
The distance a car can run on flat tires depends on several factors, including the type of tire, the vehicle’s weight, and driving conditions. Here are some general guidelines:
-
Regular Tires: If you have standard tires and one of them goes flat, it’s generally not recommended to drive more than a few hundred yards (a few hundred meters) at a very slow speed (less than 20-30 mph or 30-50 km/h). Driving further can cause irreversible damage to the tire and potentially harm the wheel or other parts of the vehicle.
-
Run-Flat Tires (Self-Supporting): These tires are designed to support the vehicle even after a puncture. They can typically be driven for up to 50 miles (80 kilometers) at speeds of up to 50 mph (80 km/h). However, this can vary depending on the manufacturer and the specific tire model.
-
Auxiliary Spare Tires: If you have a temporary or "donut" spare tire, it’s usually only meant for short distances, up to about 50 miles (80 kilometers), and at moderate speeds (usually up to 50 mph or 80 km/h). Driving longer distances on a donut can lead to its failure.
- Driving Conditions: Avoid driving on flat tires for any distance if possible. If you must, drive very slowly and avoid sharp turns or braking, as this can further damage the tire and increase the risk of losing control of the vehicle.
If you experience a flat tire, it’s best to replace it with a spare as soon as it’s safe to do so or seek roadside assistance if you’re unable to change the tire yourself.
