Stock tires on my Firebird were 25.7", so I started with 26". I didn't notice it going any faster after the 28"s, just more green lights. After hearing how taller fronts show faster on time slips I decided to A-B-A test that. (I wear my junk out testing) I borrowed a set of 26" fronts. Back-to-back-to-back testing showed about nothing. I understand the therory, but calling it one hundredth of a second difference on my car (which repeats very well) would be a stretch.
