Run-Flat tires are suitable for emergency situations. This type of tires allows safe driving in the event of significant air loss. Regardless the run-flat model you select, in case of a deflated tire, you can still go up to 100 km at no more than 50 mph (80 km/h). This way, drivers can drive themselves to a garage instead of waiting for the roadside assistance.
The structure of run-flat tires
The run-flat tires have special sidewalls that allow the tires to run in case of a puncture. These special sidewalls prevent tire attrition and their explosion. Another feature of these special sidewalls is that they have a role in the connection between the power steering and the brakes. Run-flat tires are mounted on special rims in order to make sure that the tires will not detach from the rims.
The optical signal in case of a puncture
In case of a potential damage to the run-flat tires (for example a puncture), the driver will be informed through a special display. This display uses an optical signal to indicate a tire damage. By using run-flat tires, the spare wheel is no longer required. The fuel consumption is reduced as a run-flat tire does not weigh as much as a normal tire.
