Tire pressure maintenance advice for users of the new MICHELIN ® X One wide single truck tires ® The MICHELIN X One family of truck tires is designed ® ® to replace dual assemblies on drive and trailer positions in over-the-road applications. Proper air pressure maintenance is critical to obtain optimized performance from these tires. Due to the unique casing design of the MICHELIN ® X One tires, traditional air pressure ® adjustment practices for dual tires may not apply to MICHELIN ® X One tires. In order to ensure optimal ® performance of these tires, Michelin North America offers the following guidelines: 1) Cold inflation pressure should be based on maximum axle load in daily operation. Cold inflation pressures must not be lower than indicated in the tables below for actual axle loads. For additional information, please consult the MICHELIN Truck Tire Data Book (MWL40731). 2) A 10 psi incremental change in tire inflation can alleviate most wear forms derived from vehicle anomalies, driver influence and/or application. Always refer to actual axle loads to determine the initial recommended cold inflation pressure.

If your tire's sidewall markings do not match any table listed, please contact your Michelin dealer for the applicable load and inflation table. 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. NOTE: Never exceed the wheel manufacturer’s maximum air pressure limitation. S = Single configuration, or 2 tires per axle. Loads are indicated per axle.

MICHELIN INFLATION CHARTS FOR RV USAGE ONLY 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. This table is applicable for all RV axles, whether or not they are power-driven.
