In the context of towing, what is the term for a dual-wheeled axle?

The term for a dual-wheeled axle is "dually." This designation is commonly used in the towing industry to refer to vehicles equipped with dual rear wheels on each side, which enhances stability and load-bearing capacity. Dually configurations are particularly advantageous for towing heavy trailers, as they distribute the weight more evenly and provide better traction. This setup is essential for maintaining control over larger loads, especially in challenging driving conditions.

In contrast, a single axle refers to a configuration with only one wheel on each side, which may not offer the same level of support for heavy towing applications. Heavy-duty describes the capacity or strength of a vehicle but doesn't specifically indicate that it has dual wheels. Lastly, wide axle is not a standard term in the context of towing; it may colloquially describe a broader axle but does not specifically signify a dual-wheeled configuration. Thus, "dually" is the precise term you're looking for in this context.
