Summary
If you want the highest level of traction and handling in a true street tire and are willing to give up civilized manners to get it, then an Extreme Performance Summer tire fits the bill. All four of the tires in our test deliver amazing traction and handling in dry conditions along with impressive wet grip. The newest designs offer the best outright performance, but are evolving to be much less street-friendly in the process.

Subjectively the BFGoodrich g-Force Rival S outscores the other tires by a small margin, combining strong performance with reasonable road manners. But when it comes to ultimate dry and wet performance among this group, the Bridgestone Potenza RE-71R is the top rung on the evolutionary ladder. The Kumho Ecsta V720 gives the Potenza RE-71R a run for its money by delivering impressive dry performance, but brings along road manners so extreme that it's not for the faint of heart and not well suited to daily commuter duty. The Hankook Ventus R-S3 (Version 2) holds its own against tough competition, but from an outright performance perspective it's clear that newer designs are a little faster.

    Oh wow, I didn't know Kumho was back at it. Strangely absent is the Dunlop Z2 Star Spec, however.

      My guess is that one of those tire manufacturers paid for the test that day and told the other guys to keep it a secret so Dunlop wouldn't show up and destroy everybody.

        Good post Mike!

        Always interesting to see how the new batch of tires perform against each other.

        Having used these tires for 3/4 of a season so far i've really noticed this, even with a couple of co-drives. I haven't even swapped my tires front to back yet and looking at them you'd think I've only done a few events on them.

        I'm excited that these will easily last 2 seasons, maybe even 3...I'm ok giving up a bit of grip for this luxury.

          I think that's because it's not new anymore - was released last year, no?  All the ones in that list iirc were released this year.
