I originally had Goodyear NCT5's fitted to the vectra, but they were way to expensive for what they are, then I moved onto falken ZE512's which I thought were the worst tyre I have ever had on any car as the would slide on corners in the wet and were just totally rubish. Then I deciced to put Falken ZE912's on, and they are great value for money, at half the price of the original good year NCT 5, they seem to be a lot better tyre, and give plenty of wet and dry grip also positive feedback through the wheel, I wud recoment anyone to buy these tyres, I have done 10000 miles of hard driving and there is still plenty of tread.
