Conti has made 2 million ContiSeal tyres

ERJ staff report (DS)

Lousado, Portugal -- The Continental tyre plant in Lousado, Portugal has made the two millionth tyre with ContiSeal technology.

The 235/45 ZR 17 dimension tyre will be mounted on a Volkswagen Passat as original equipment. Continental has been manufacturing car tyres with ContiSeal technology since 2008. These tyres are sealed with a viscous mass that is mounted on the inside of the tread layer. In case of punctures by nails and screws the resulting hole is immediately closed without pressure loss and the journey can proceed trouble-free.

The tyres are manufactured in 8 sizes and are used in both the original equipment and replacement markets. Continental expects the approval to come during this year for original equipment from other manufacturers.

The key drawback of the technology is a significant increase in rolling resistance.
