New tire offers great traction, long life, low rolling resistance

A New version of the X One wide single tire for drive applications was rolled out by Michelin Americas Truck Tires. The X One XDN2 tire was introduced during the 2008 Great American Trucking Show in Dallas, Texas.
The XDN2 is the first X One tire in North America to utilize multiple Michelin Durable Technologies (MDT), according to Don Baldwin, Michelin product manager. The tire will be available to end-users in November 2008.
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 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% lower than its dual XDN2 tire counterpart. Michelin's 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 normally the challenge with deep-treaded, heavily-siped tires. Also a first for an X One tire is the tire's open shoulder tread design for additional traction.
The XDN2 tire will be available to end-users in November 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 XDN2 will replace Michelin's X One XDA-HT Plus tire.
