Where are the snow chains located on a single rear axle apparatus?

The correct answer highlights that snow chains are typically placed on the outer drive wheels of the rear axle of a single rear axle apparatus. This is important for improving traction in snowy or icy conditions. The outer drive wheels are the specific wheels that have direct contact with the road when the vehicle is in motion, making it crucial for them to have enhanced grip to ensure safe operation.

This positioning helps to maximize the effectiveness of the chains, as they can better penetrate the snow and hold onto the surface beneath, providing essential traction to maneuver the vehicle. When snow accumulates, the rear axle’s outer drive wheels encounter the most resistance, thus benefiting the most from the enhanced traction offered by snow chains.

In contrast, other areas mentioned do not provide the same benefit. For instance, placing chains on the front axle or inner drive wheels would not effectively address the challenges faced by the rear wheels during driving in slippery conditions. Additionally, side mirrors have no functional role regarding snow chains, as they are solely for visibility purposes and do not contribute to traction on the road.
