Because with a wide base there is less scrubbing of the wheels.
Think of a vehicle that is 3 feet wide and only 6 inches long. When it is skid-steer turning, there is almost no scrubbing of the wheels, because each wheel is moving in the plane of the wheel.
Now think of a vehicle that is 3 feet long and only 6 inches wide. When it is skid-steer turning, each wheel is moving sideways (perpendicular to the plane of the wheel).
Here's a sketch.
