Inside the tread of the tire is a coat of sealing material. This prevents a loss of pressure when the carcass is damaged. Not depending on if the object which damaged the tire is still in the tire.
Step 1:
An object is driven into the tread. The sealant adheres to the object.
The sealant reacts to the damage and closes the hole.
Step 2:
The object is removed from the tread.
The sealant is pulled via the object into the hole, when the object is removed from the tread.
This way the hole is closed by the sealant.
CAUTION:
The seal inside technology does not guarantee a repair of the tire after damage.
Unlike run flat tires seal inside tires cannot be driven with low air pressure or flat.
