Run-flat tires are specially designed tires 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 travel for a limited distance—typically around 50 miles—at reduced speeds, usually up to 50 mph. This feature can provide added safety and convenience, as drivers can reach a service station without needing to change a tire immediately. These tires are commonly found on luxury vehicles and sports cars, as well as some SUVs and trucks. While they offer benefits like reduced risk of blowouts and the elimination of the need for a spare tire, they can be more expensive than traditional tires and may have a stiffer ride. Regular maintenance and monitoring of tire pressure are still essential for optimal performance.
