I hope this answers the questions some have about the use of alternate materials for tire balancing.
The Use Of Internal Balancing Materials and/or Coolants In MICHELIN® Truck Tires
The use of internal balancing materials and/or coolants (such as powders, liquids, gels and/or beads) in MICHELIN® Truck Tires does not automatically affect the tire warranty unless the internal balancing material and/or coolant has a high water/moisture content or that it is determined that the internal balancing material and/or coolant has adversely affected the inner liner, casing plies, or the performance of the tires.
Prior to using any type of internal balancing material and/or coolant, Michelin strongly recommends that the customer make sure the internal balancing material and/or coolant has been tested and certified by the internal balancing material and/or coolant manufacturer as being safe for use in tires. Water/moisture content testing should be included in the certification process. Any product with a water or moisture content greater than 3% as measured by the Karl Fisher Method (ASTM D6304) will automatically void any mileage, number of retreads and/or time warranty.
In addition to the forgoing, please refer to the Michelin Truck Tire Operator’s Manual and Limited Warranty (MWE40021) for a general discussion of what is and is not covered by the warranty.
NOTE: Please consult Michelin prior to using internal balancing materials and/or coolants in any MICHELIN® tires that have sensors in them. The internal balancing materials and/or coolants may adversely affect the performance of the sensors.
For additional information, please contact your local Michelin sales representative or contact Michelin using the website at www.michelintruck.com.
