As usual for a magazine test, they cocked it all up! They increased the radius almost 1 Inch by going to a 18" wheel. Had they gone wider, but kept the same rolling radius, the results would have favored the wider tire. They also chose an under-powered car to help prove their point.
Magazines rarely do an apples-to-apples test to answer a question. They start with the results they want to prove, and arrange a test to make it so.
Ah, you beat me to it!
