Michelin has unveiled the latest tire in its X One wide single tire line: the Michelin X One XDN2 tire.

The on-highway drive tire, introduced at the 2008 Great American Trucking Show, is the first X One tire in North America to use multiple Michelin Durable Technologies (MDT). The tire will be available to end-users in November 2008.

"This tire takes the traditional compromise between traction, long-life and fuel efficiency, and throws it out the window," said Marc Laferriere, vice president of marketing, Michelin Americas Truck Tires. "By utilizing two different Michelin Durable Technologies, the X One XDN2 tire delivers significantly increased tire life and exceptional, uncompromised traction, complementing the significant fuel efficiency gains of a Michelin X One wide single tire."

The X One XDN2 tire makes no compromises in traction or mileage, and also delivers fuel efficiency levels approaching Michelin's most fuel efficient truck tire, the X One XDA tire.

Through MDT, the X One XDN2 tire is able to reduce the number of flexing sidewalls from four to two, when replacing dual tires, which significantly lowers rolling resistance-15 percent lower than its dual XDN2 tire counterpart. The Michelin wide single tire is made possible by the Infini-Coil Technology -- more than a quarter-of-a-mile of steel cord wrapped circumferentially around every X One tire from sidewall to sidewall. The Infini-Coil reduces casing growth and stabilizes the contact patch, reducing irregular wear.

The XDN2 tread pattern incorporates Matrix Siping Technology -- corrugated grooves in the tread block that provide a zigzag appearance. These wavy grooves lock the tread block as it moves through the contact patch, providing both tread block rigidity and exceptional traction, while resisting tread scrubbing, as is the normally the challenge with deep-treaded, heavily siped tires. Also a first for an X One tire is the X One XDN2 tire's open shoulder tread design for additional traction.

The Michelin X One XDN2 tire will be available to end-users in November 2008 in a 445/50R22.5 size (equivalent to a 275/80R22.5 size), with a 455/55R22.5 size (equivalent to an 11R22.5 size) becoming available in December. The X One XDN2 tire will replace the Michelin X One XDA-HT Plus tire.
