Michelin America Truck Tires’ XZA3 + Evertread steer tire incorporates a dual-compound tread designed for improved fuel efficiency and mileage, and to meet California Air Resources Board requirements and U.S. Environmental Protection Agency SmartWay certification. The dual compounds include a tough wear-resistant compound for the five bands of tread that actually contact the road, and another one underneath that helps keep the casing cool and supports all the tread bands and also composes the shoulder rib.
The two different rubber compounds are designed to work together to help provide long life and resist irregular wear while flexing more easily, helping to keep the casing cool and optimize fuel economy. A thicker damage-resistant inner liner and a robust bead that employs Michelin’s rectangular bead bundle helps keep the bead stable on the rim.
