Run-flat technology refers to a type of tire design that allows a vehicle to continue driving even after a puncture or loss of air pressure. These tires are built with reinforced sidewalls that support the weight of the vehicle, enabling it to maintain stability and control for a limited distance, typically up to 50 miles at reduced speeds. This feature can enhance safety and convenience, as drivers can reach a service station without needing to change a tire immediately. This technology is commonly found in many modern vehicles, including those from manufacturers like BMW and Mercedes-Benz. Run-flat tires eliminate the need for a spare tire, saving space and weight in the vehicle. However, they may have a stiffer ride and can be more expensive than traditional tires, making it essential for drivers to consider their specific needs when choosing tires.
