These are fine educated statements made by persons who obviously have a lot of knowledge in this area. Nevertheless, the real world data collected by Car and Driver indicated that, comparing identical brand wheels and tires (19 vs 18), the 18 inch versions had better acceleration, better roadholding, better ride, better fuel mileage, lower total (wheel + tire) weight, and lower total cost.
