There is merit of course in a back-to-back test of superbikes. They're a big ticket item, but for many of us, they are a once-in-a-blue-moon upgrade. Tyres, on the other hand, are far more readily affordable, and are a consumable part; they will eventually wear out, through use or incurable punctures, and will need replacing. With such a range of options on the market, each with competing marketing claims, knowing what you actually stand to gain between one tyre or another is nearly impossible to work out.
