What Is a Dually Truck?

Although all trucks with dual rear tires are referred to as dually, there is more to these vehicles than just extra tires. For starters, rear dually tires are generally larger than standard truck tires. Dually trucks also have stronger suspension systems to help distribute and carry the extra weight. Because of the extra-large towing capacity, dually trucks are often used in construction and farming where heavier equipment is needed.
