Final answer:
A truck with two tires in the back is called a dual rear wheel truck or a dually. This configuration provides better stability and weight distribution, especially when carrying heavy loads or towing large trailers.
Step-by-step explanation:
In automotive technology, a truck with two tires in the back is called a dual rear wheel truck or a dually. The term 'dually' refers to the two tires installed on each side of the rear axle. This configuration provides better stability and weight distribution, especially when carrying heavy loads or towing large trailers.
A dually truck has increased towing capacity, improved traction, and better handling compared to trucks with a single set of rear tires. The additional tires help distribute the weight more evenly, reducing wear on individual tires, and improving overall vehicle performance.
Overall, a dual rear wheel truck is a popular choice for heavy-duty applications and for those who require enhanced stability and load-carrying capabilities.
