I am happy with my Nankangs. I am not after ultimate roadholding or anything like it as all of my driving will be down the main highway at 110 km/hr or less or on a secondary road at much less.
The issue with Nankangs is not one of ultimate roadholding but the emergency brake or the emergency swerve (or a combination) occurring in the wet. I wouldn't want to rely on Nankangs helping me out in such circumstances.
Bonne chance! Peter
