The basic benefit is continued mobility in case of a loss of air pressure.
In order to achieve a level of total mobility, Pirelli has developed two different technologies: the SEAL INSIDE, a Self Sealing technology which contains an extra lining within the tire that self-seals, and the RUN FLAT, a Self Supporting Technology with a rigid sidewall within the tire.
Seal Inside technology allows the vehicle to keep running without losing air pressure even after the tire has been punctured by an external object, covering almost 85% of the possible accidental causes of pressure loss.
A Seal Inside tire won’t leave you stranded in the middle of the countryside or in a bad neighborhood. Just drive home.
The Seal Inside technology does not need dedicated rims and TPMS (Tire Pressure Monitoring System) to be used safely on a vehicle; it can be used on any kind of vehicle depending on the tire size.
Pirelli’s Self-Sealing tires are made up of a material that forms a sealing layer, which is placed inside the tire in the area corresponding to the tread pattern. The material tightly blocks every possible air leakage in the event of a puncture that passes through the tire, with or without an external object still present.
The Seal Inside tire deals immediately with the hole and, in most cases, its fast and effective action means that the driver won’t even realize that the tire has been punctured.

The Self-Supporting Run Flat tire offers stability and reliable handling to keep control of your vehicle in the event of a puncture.
A flat tire won’t leave you stranded in the middle of the countryside or in a bad neighborhood. Just drive home.
No need to change the flat tire immediately. First drive home and then change your tire. Comfort for you and your family. A flat tire won’t mean missing a flight or an important meeting.
Pirelli Self-Supporting Run Flat™ tires are the result of the innovative Pirelli MIRS™ production process entirely overseen by computers that guarantees an end result characterized by the highest standards of quality and reliability.
The absence of the spare wheel means more freedom during car design development, reduced vehicle weight ... and more trunk space for the end user.
