Composition for reducing tire-wheel assembly imbalances, force variations, and/or vibrations

A composition for reducing weight imbalances, force variations, and/or vibrations in a tire-wheel assembly comprising:

• a first plurality of particulate for positioning within the tire-wheel assembly, where each particle in the first plurality of particulate comprises a first material and is characterized as having low energy absorption capabilities;
• a second plurality of particulate for positioning within the tire-wheel assembly, where each particle in the second plurality of particulate comprises a second material and is characterized as having elevated energy absorption capabilities relative to each particle of the first plurality of particulate,
• the first material being different than the second material, and
• where each particle in the first plurality of particulate is characterized as having a shore D hardness equal to or greater than 50, where a majority of the first plurality of particulate is at least 0.841 mm in size, and where the first plurality of particulate is formed of a plastic and where each particle in the second plurality is formed at least partially of an elastomeric material.
