The Hankook SEALGUARD sealing technology applied in the Hankook 19-, 20- and 21-inch dimensions for the VW ID.4 automatically seals punctures up to 5mm in diameter within the tire's tread area. SEALGUARD offers the advantage that even in the unlikely event of a nail puncture, for example, a trip can be continued without any problems and the tire does not need changing. Therefore, a spare wheel no longer needs to be carried in SEALGUARD-equipped vehicles, providing additional space in the boot, saving weight, and eliminating the need for a potentially dangerous wheel change at the roadside. In addition to their safety benefits, tires equipped with Hankook's SEALGUARD technology continue to offer the usual comfort, as their basic construction does not differ from tires without SEALGUARD.
