Kumho Tire, South Korea’s second-largest tiremaker, said Friday it will market the first indigenous self-sealing tires that can reduce overall maintenance cost for drivers.

The so-called self-sealing tires took more than two years to develop and use special jell technology that immediately fills up any holes, helping to maintain consistent air pressure despite punctures to the tread.

This mechanism allows for normal operation with a punctured tire whereas other tires would go flat. If properly maintained with regular checkups, the new tires can reduce overall maintenance service time and cost for car owners, according to the company.

“Tests have shown almost no change in air pressure even when the tire is completely punctured by sharp objects such as nails,” a Kumho spokesperson said.

He added that while the new tires, made based on the company’s premium product Majesty Solus, are about 10 percent heavier than conventional products, their handling characteristics remain the same. (Yonhap News)
