Bigger is less able to maintain road contact over medium-sized bumps; the smaller wheel will follow the contour better. Bigger will generally weigh more, which means a higher ratio of unsprung to sprung weight, not good because wheel bumps will have more shock effect on the rest of the car. For the same width the bigger wheel will have a larger footprint. This generally means a better grip on dry pavement and poorer (more likely to hydroplane) on wet pavement.

The difference is performance depends in large part on what it is being used for.
To me, the most important difference is bearing speed. A bigger wheel turns slower than a smaller wheel for the same linear speed and is easier on the bearings. Also, a bigger wheel does better on a rough surface.

it s the same because of the moment of inertia.
