【Tires】Even if a nail is stuck, the air does not escape! A comfort tire that automatically seals “puncture holes”

Continental Tires Japan has released the comfort tire "ExtremeContact XC7," equipped with advanced technology. This tire achieves high-level quietness, comfort, and wet performance, aiming to enhance driving satisfaction.

Equipped with ContiSeal and ContiSilent as standard across all sizes

The new comfort tire "ExtremeContact XC7," which achieves a high level of both safety and comfort. The reason for this is the high-adhesion sealant layer. Even if damaged within a diameter of 5mm, this high-adhesion sealant layer arranged on the inside instantly seals the hole. By suppressing sudden drops in air pressure, it supports safe driving.

It’s surprising that this sealing effect is guaranteed for the typical tire lifespan of 10 years.
*However, depending on the damage condition, it may not prevent air leakage. This product is designed to suppress drops in air pressure and does not guarantee complete puncture prevention.

Using multiple approaches to reduce road noise, it adopts a wideband noise reduction. A polyurethane foam applied to the inside of the tire absorbs the cavernous resonance sound produced during rotation. Additionally, small protrusions within the tread grooves optimize air flow, suppressing certain unpleasant frequencies.

With the added vibration absorption effect of the sealant layer, vibrations from the road are minimized. It is achieving an unprecedented level of high-quality and quiet interior environment.

When considering long drives or carrying family, ride comfort is essential. The tread structure that flexibly makes contact with the ground, combined with a special compound that uses a high molecular polymer network, effectively absorbs shocks from the road. It balances stable handling with comfortable driving.

To enhance safety on wet surfaces, drainage efficiency is also pursued. The dual-channel drainage design applied to the central block of the tire and the optimization of the main grooves improve the discharge speed. Furthermore, by adopting a blade angle design that instantly cuts through the water film, it helps suppress hydroplaning, providing reliable grip even on wet surfaces.
