The new
Michelin Pilot Super Sport is the highest rated tire in the Max Performance Summer category when compared with the Bridgestone Potenza S-04, Continental ExtremeContact DW, and the Pirelli P Zero. The Pilot Super Sports reach 1.07g dry cornering grip.

The Hankook Ventus V12 evo K110 isn't even close to any of the tires in the above group (all of which exceed 1.0g cornering grip) whereas the VentusV12 only generates 0.90g of dry cornering grip.

If you're looking for value, the V12's might very well be a good choice in terms of performance/price. However, you should also look at the Dunlop Direzza DZ101, Kumho Ecsta SPT, and the Yokohama S.drive which are comparably priced yet perform somewhat better than the V12's.
