ContiSeal

A self-sealing tire today no longer belongs solely to the realm of science fiction or secret agents. On the contrary, Continental has been offering a self-sealing tire since 2007, when it first introduced the tire with ContiSeal™ technology at the Geneva Motor Show.

ContiSeal™ is a technology that enables automatic sealing of the tire in case of a typical puncture of the tread. This technology only works for smaller punctures, up to about 5 mm in size, which corresponds to a puncture from a nail or screw. Another advantage is that the tire remains sealed even if you remove the object that pierced the tread. Thus, the driver does not need to deal with the puncture by immediately changing the tire or using a repair kit. They can simply continue driving or try to remove the clicking nail.

Principle of ContiSeal tire operation:

The inside of the tire is filled with a relatively thick layer of black viscous sealing compound. This compound is capable of sealing the resulting hole from the inside of the tire in case of a puncture. The sealing occurs immediately with minimal loss of pressure. According to statistics, such a tire can handle up to 80% of punctures on its own.
