The presence of the tyre burst causes inconvenience, danger, anxiety and panic, and people never feel adequately prepared for it. Even though almost all modern cars are equipped with spare tire and tire or flat tire repair kits (maneuverability), not everyone has the expertise and ability to manage each process. Even for people who do have learend about machinery, tire repair on the roadside is very dangerous, and there is a constant traffic threat to repair cars on uneven ground and under other serious dangers.
When the tire is blown out or damaged, the flat run flat tire can prevent the vehicle from being unable to drive normally. Instead of repairing on the roadside, run flat tires can keep the vehicle running. In most cases, the car can reach the home or the nearest service station.
Conventional auto tyres require proper inflation and air pressure to function. In the event of air pressure loss caused by a tyre burst or other tyre damage, the tyre becomes flat and does not function. A flat run flat tire also requires air pressure to function properly. However, their unique construction includes a "backup plan".
A flat run flat tire is to prevent the effects of deflating when punctured and to allow the vehicle to continue to drive at reduced speed and at limited distances.
Unlike standard tires, flat run flat tires do not usually flatten out. Even when air pressure is completely lost, the reinforcing structure of the flat run flat tire keeps the sidewall upright and allows the tyre to roll. The tire sidewall of a flat run flat tire supports the weight of the vehicle even without air pressure. So, there are more and more tyre manufacturers producing this type of tire.
After losing air pressure, a flat run flat tire may reduce maximum speed or possible distance depending on the severity of damage to the tire. A flat run flat tire has the additional benefit of preventing a dangerous tire from bursting. Tyre blowouts cause thousands of accidents each year, resulting in hundreds of drivers injuries or deaths. A flat run flat tire may be known for its ability to prevent typical tire bursts and gradual air pressure loss, but a reinforced tire sidewall can also stabilize and control the vehicle immediately when a tire bursts.
