So looking at tires/wheels combos, i was wondering what you would rather have, less wheel weight? or greater tire width? for example: would your rather have 15 inch tires with a weight of 9.5 pounds and a tire width of 195 or the 16 inch tires with a weight of 13.5 with a tire width 205? Is the unsprung weight or more rubber on the road more important? I also suppose there is other factors that come along such as the size of the sidewall, etc.
