and with smaller wheels wouldent you have less traction because of less surface area

No, because the overall robot weight is the same. If the surface area goes down, then the concentration of weight on the area goes up. Traction does not change.

Small wheels provide less cost, less size, and you need less reduction before the wheel. The only thing they lack is provided ground clearance. But that can be worked around.
