The rolling diameter is only a hair different (30.03 vs 30.18), so your speedo won't notice much. There's really no advantage besides cool factor. The '20's have less sidewall and will add unsprung weight, which are both disadvantageous factors for handling and may give you a harsher ride to boot. Radials work by keeping the tread stiff and flat while letting the sidewall flex, and less flex directly affects traction in the corners and provides less cushion and poorer conformity over rough surfaces. The only true advantage of a larger rim is extra brake ventilation.
