I recently tested Ultra High Performance All-Season tires on a Real World Road Ride and Performance Test Track Drive.
Yokohama AVID ENVigor
During the Real World Road Ride, I found the Sumitomo and Pirelli to have the quietest ride and best comfort. The Dunlop was my least favorite in those areas. But during the dry Performance Test Track Drive, I found the Dunlop to have excellent cornering, handling and braking. The Sumitomo and Pirelli were also very good. When driving on the Yokohamas, though, the vehicle did not feel nearly as planted around corners or through the slalom.
Official results will be online soon. Here is more information on our testing program.
