ABSTRACT:
The invention relates to a motor vehicle wheel capable of improved dynamic self-balancing against imbalancing forces in the X, Y and Z planes. The wheel comprises a hub portion and an annular rim portion integral with the hub and extending circumferentially around the hub portion. The rim has inner and outer flanges adapted for securing a tire to the wheel. The rim portion is provided with a circumferential integral annular channel containing a quantity of balancing fluid having a relatively high boiling point and a relative low freezing point and whose remaining physical properties are not negatively affected by adverse environmental conditions. As the wheel rotates, the fluid spinning within the channel will substantially instantaneously counteract imbalances within the wheel and tire combination caused by irregularities due to, e.g., valve stems, dents and attached road debris by migrating to a location within the channel directly opposite the imbalancing force.
