A few years ago I conducted some coast down tyre testing and the 25mm tyres did indeed prove to be faster, about time I conducted that test again… German TOUR magazine recently conducted a test of tyre width, and found a 28mm tyres faster with lower rolling resistance than both the 23mm and 25mm tyres they tested, with the difference between the slowest and fastest tyres a claimed 9.5 watts, a margin not to be sniffed at.
