Test results are in for some of the top autocross tires for this season. The test featured the BFGoodrich g-Force Rival S, Bridgestone Potenza RE-71R, the Hankook Ventus R-S3 Version 2 (some of my early picks for this year's top contenders), as well as the Kumho Ecsta V720, which was a late addition to the field of SCCA eligible competitors.
Some of my takeaways from this test: The Bridgestone Potenza RE-71R brought the overall highest grip level. The Rival S had impressive levels of grip with higher subjective scores for road manners. Kumho was a bit old-school in its approach, abandoning the pretense of civility to deliver high grip and sharp handling in an uncompromising package. Hankook's Ventus R-S3 Version 2 remains a strong performer, but as an update rather than a whole new model it does not quite keep up with the newest competitors.
The Bridgestone lapped fastest both in the wet and dry, though the BFGoodrich posted slightly shorter stopping distances, while Kumho's offering had just a hair more wet cornering grip.

All of these tires are excellent entries into the popular and growing Extreme Performance Summer category. They blend real-world road capability with outstanding levels of traction and durability to survive the demands of weekend track warriors.
