Pirelli displays “Seal Inside” technology

During the launch of the Pirelli’s Cinturato P1 tyre earlier in the year, Pirelli showcased a new self-sealing technology currently available in original equipment tyres the Italian brand supplies to Volkswagen. Named “Seal Inside”, the technology allows the tyre to “fix itself in the event of a puncture, allowing the driver to carry on without having to change the wheel,” according to Pirelli. It was developed by Pirelli’s Research Department with the emphasis on safety, helping to maintain the pressure and integrity of a punctured tyre and preventing 85 per cent of the possible causes of a deflation.

Behind the tread of the tyre a layer of sealant prevents air escaping whether or not the object that has penetrated the carcass remains in place. Seal Inside works immediately on the area that has been punctured, leaving the tyre’s performance and safety characteristics “uncompromised”. Pirelli says motorists “will not even notice that a tyre has been punctured”.

The technology lines up alongside Run Flat technology, sharing safety and performance preservation characteristics, though Seal Inside promises to retain rolling resistance, comfort and noise performance on both wet and dry surfaces.
