Dry - Excellent and can't fault them.
Wet - Scary, even with an AWD performance car. I don't belive these tires to be a safe selection when driving on wet greasy roads in a spirited manner, in particular on exiting roundabouts.
Standing Start - Wet and dry grip excellent, nil wheelspin in the Golf R; obviously the AWD plays a major factor.
Overall, good in the dry, but give nil confidence on wet greasy roads in the UK.
