XZA®-1+

All-position radial optimized for steer axles in line haul and limited regional applications.

The "original" shoulder decoupling groove helps resist irregular wear in slow wear rate applications.

Miniature groove wall sipes help inhibit the onset of irregular wear while helping to improve traction on wet surfaces.

Approved for use on EPA SmartWay® certified equipment and meets California's CARB requirements.

Rectangular bead bundle - - a Michelin® exclusive - simulates a solid steel rod "strapping" the tire onto the wheel. This design stabilizes the entire bead region and minimizes fatigue in order to extend casing life.

Full-width, elastic protector ply - helps protect the working pliesfrom bruising and penetrations, minimizing downtime.

Tightly-controlled crown architecture, uniform undertread and flat crown radius - help provide long, even wear, and retreadability.

Miniature sipes in the groove walls and variable groove angles - help reduce irregular wear, contribute to the outstanding traction of the tire, and help improve overall performance.

The original shoulder groove design - helps deliver outstanding traction while promoting great resistance to uneven shoulder wear, to keep the XZA®-1+ tire on the road for a long time.
