XZA®1

Even-wearing, all-position tire optimized for heavy axle loads in line haul and limited regional applications.*

Miniature sipes in groove walls and variable groove angles help reduce irregular wear and improve overall performance.

Full-width elastic protector ply helps protect the working plies from bruising and penetrations.

Flat crown radius helps enhance wear and tread life.

LOAD & INFLATION PRESSURE

Load and Pressure tables are only for RV usage. Given loads are per axle end.

For RV use only, Michelin displays tire loads per axle end in the load and inflation tables, as we recommend weighing each axle end separately and using the heaviest end weight to determine the axle's cold inflation tire pressure. For control of your RV, it is critical the tire pressures be the same across an axle, while NEVER exceeding the maximum air pressure limit stamped on the wheels.

Industry load and inflation standards are in a constant state of change, and Michelin continually updates its product information to reflect these changes. Printed material may not reflect the latest load and inflation standards.

In the load and inflation tables, SINGLE means an axle with one tire mounted on each end, while DUAL means an axle with two tires mounted on each end. The loads indicated represent the total weight of an axle end in an RV application. When one axle end weighs more than the other, use the heaviest of the two end weights to determine the unique tire pressure for all tires on the axle. The maximum cold air pressure for each axle may vary, depending on their weights. These tables are applicable for all RV axles, whether or not they are power-driven.
