The first test tackles performance in dry conditions on a handling course. The results are fairly predictable. The largest 19-inch wheels with the shortest, stiffest sidewall was the fastest by just over a second on the race course. Benson says they improved the feel of the car, too. Wet pavement really changes things, though. On the water-soaked course, the 17-inch wheels and tires turned in the fastest time, with a similar time difference as on the dry course. Benson also preferred the feel of the 17-inch wheels on the wet track. Finally, for comfort, the 17-inch tires also came out ahead, but just barely. They fell short in the noise test.
