New X-One tire lightens the load

DALLAS, Tex. – Michelin launched a new tire design at the Great American Truck Show in Dallas, Texas last month. The X-One is being marketed as a more fuel-efficient alternative to traditional dual tires used in the trucking industry. The X-One replaces dual tires with just one tire on tandem-axle tractors and trailers.

The X-One is being introduced initially in a 445/50R22.5 size in a drive pattern (XDA) and a trailer pattern (XTA). This particular size is interchangeable with dual low-profile 22.5 tires for simpler fitting.

According to Michelin, going from two wheels to one per axle end reduces weight, lowers rolling resistance due to compounding by reducing the number of flexing sidewalls, and improves fuel economy.

“Less weight and lower rolling resistance results in reduced fuel consumption to meet the specific needs of over-the-road truckers,” says Michelin vice president of marketing Randy Clark. He adds that drivers with test fleets say the X-One has improved responsiveness and handling over conventional low-profile 22.5 tires. Fewer wheels also mean fewer tires to mount, dismount, inspect and rotate, resulting in less maintenance and driver downtime, he says.

Currently, the 445/50R22.5 X-One XDA is available for OEM 6X4 tractors purchased through Freightliner, Sterling and Western Star, and for replacement purchase through authorized Michelin dealers throughout North America. n
