It is very interesting. From what I read they did multiple test and designs to come up with this pattern. Not sure if it will work but the following is a link to a video about the Sessanta.

Here is a section out of a advertisment for features and benefits:
Parametric Design - Optimal design quality: profile, construction, design and contours selected according to mathematical formulae for each size.
Handling Tuned Tread Compound (HTTC) Extremely high tracking power, allowing faster cornering Measured correction of the car is possible on bends.
HTS+ (Handling Tuned Sidewall) principle with robust outer shoulders and sturdy sidewalls Very direct steering feel Optimal contact with the road surface.
Two rayon carcass layers make the tyre stable and sturdy during handling Maximum resistance to lateral forces The car stays more controllable in the most crititcal situations.
Of course it is all just words if it doesn't perform but, personally, between the design, the cost and the reviews I got sold. I hope they perform like they are supposed to. I have 315/35/17 on the rear and they were $200 ea., the fronts - 245/45/17 were $160 ea.
