Sumitomo has begun implementing the Coreseal technology in mass production.
Falken’s first tire to feature an integrated tire sealant technology that immediately seals punctures and minimizes the risk of a flat tire will be the Falken Euroall Season AS210 model that will go on sale next month.
The Coreseal technology was presented at the Tokyo Motor Show still in 2015, and similar technologies have already been implemented by other tire makers, such as Continental, Michelin, and Pirelli. An additional sealing layer of highly viscous material is placed inside the tire, which seals holes in the tread up to 5 mm wide, preventing air loss and allowing you to continue driving, thereby eliminating the need to change the tire in the event of a puncture.
«CORESEAL is a simple solution to a disruptive problem," says Andreas Giese, senior manager corporate planning/product planning at Falken Tire Europe. «Now you no longer have to change a tire or wait for roadside assistance, you can simply continue your journey. CORESEAL is a significant step in making tires smarter and more efficient.»
Initially, the self-sealing tires were launched at the German and Austrian markets in July this year in size 235/55R18 104V XL; later on, they will also be available in size 225/50R17 98V XL.
Besides Coreseal, the company is actively engaged in the development of other «spareless» tire products, such as FEXM (Falken Extended Mobility Technology) tires featuring Run-Flat technology, and the GYROBLADE «airless tire» technology, which will eliminate the need for compressed air entirely. As the company notes, these technologies eliminate the need for spare tires, not only contributing to resource savings, but also reducing vehicle loads for improved fuel efficiency.
