Run-flat tyres are specially designed tyres that allow a vehicle to continue driving even after a puncture or loss of air pressure. They have reinforced sidewalls that support the weight of the vehicle, enabling it to maintain stability and control for a limited distance, usually up to 50 miles at reduced speeds. These tyres eliminate the need for immediate roadside assistance or changing a flat tyre, providing added convenience and safety. However, they may have a stiffer ride compared to regular tyres and can be more expensive to replace. Regular maintenance and checks are still essential for optimal performance.
