There is more to it than just the total weight, the diameter is a factor. It is the weight at a distance, it is the inertia. The closer the rotating weight/mass is to the centerline the lower the inertia is. Inertia relates to acceleration, if you could care less about vehicle acceleration you might not notice the difference.
In something like a heavy truck caring a load, a large inertia with slow acceleration can be an advantage. A stripped down hopped up car with low gearing would want low inertia to help acceleration.
