Why do some trucks have double axles and some don t?
The technical term is “dual rear wheel”, called dually or DRW for short, and it all comes down to increase safety and stability when towing. With two wheels instead of one, a truck can distribute the weight of a payload more evenly and have improved stability when towing loads like horse trailers or large campers.
What is the advantage of dual rear wheels?
A dual rear-wheel truck (DRW) – often referred to as a dually – is a heavy-duty pickup truck with two rear wheels on each side, allowing more road contact and width for greater stability, balance, and traction while driving.
Why do trucks and buses generally have double wheels at the rear end?

Why do some trucks have extra wheels?
The amount of weight that a truck can have per axle is decided by the department of transportation in each U.S. state. When you load a dump truck with gravel, the weight can easily exceed the per-axle limit, so the extra wheels/axles are lowered to make the truck legal.
Do you need CDL for F350?
The Ford F-350 only requires a CDL by federal law if the gross combination weight rating exceeds 26,001 pounds. As the curb weight (weight of an empty vehicle) of the F-350 is far less than 26,001 pounds, you will not need a CDL for normal, everyday driving. All states adhere to this federal regulation.
