What Are Run Flat Tires?

Run flat tires, also known as extended mobility tires or zero-pressure tires, are designed to provide a temporary driving solution in the event of a puncture or rapid air loss. Unlike conventional tires, run flat tires feature reinforced sidewalls that allow the tire to support the weight of the vehicle and continue rolling for a limited distance and speed, even when completely deflated.

The primary difference between run flat tires and traditional tires lies in their construction. Run flat tires incorporate additional reinforced layers or inserts within the sidewall, creating a sturdier structure that can withstand the vehicle’s weight without air pressure. This design eliminates the need for a spare tire, as the run flat tire can be driven on for a certain distance, allowing the driver to reach a safe location for repair or replacement.

One of the main advantages of run flat tires is the increased safety and convenience they offer. In the event of a puncture, drivers can continue driving at a reduced speed, typically around 50 miles per hour, for a distance of up to 100 miles or more, depending on the manufacturer’s specifications. This eliminates the need to change a tire on the side of the road, which can be dangerous and inconvenient, especially in adverse weather conditions or remote areas.

However, run flat tires also have some drawbacks. They tend to be more expensive than conventional tires, and their reinforced construction can result in a harsher ride quality and increased noise levels. Additionally, once a run flat tire is damaged or punctured, it cannot be repaired and must be replaced, further increasing the overall cost of ownership.
