Based on the final drive ratio, the drive shaft spins and has to accelerate/decelerate over 4x faster then the wheels/tires. The effective radius of the rotating mass is, of course, much greater on the wheels/tires than it is on the driveshaft.

Either way, having less mass to propel and change the speed of is always a good thing.
