Abstract: Run flat or self-supporting tires are specifically designed to keep working even after a puncture for a short time. So if tire gets puncture on a hot day, dark night, they can safely drive home or to the nearest garage to get the tire fixed, there's no need for an inconvenient roadside tire change. Because of its special design, run flat tires often raising the risks of a potentially dangerous tire blow out. This can also remove the additional weight of the vehicle's spare tire, equipment for better balance, jack and tools in the vehicle for better balance, fuel efficiency and fluid handling.Self-supporting in the tire and helping the driver when the car suddenly breaks down, it can comfortably support the car's weight in the event of a puncture.The special materials on the running surfaces are tougher than on normal tires, helping the tire to bear the vehicle's weight and provide continuous driving to the nearest workshop or our house.These are pneumatic tires that are designed to withstand deflation when punctured and that will allow vehicles to drive for limited distances. Run flat tires have an additional internal structure providing support in deflation situations.The popularity of run flat tires is expected to grow as customers continue to rate high on the list of features they are looking for in a car.Two run-flat systems are described i.e.Overwork NLR and Michelin ACM insert rings.
