205/50r16s, for a 850 T5. The Avon ZT7s on it currently are not the greatest, providing sub-par traction. Seen a sale (£67pw) on Hankook Ventus Prime 3s - which seems to have very good reviews, are they as good as the reviews suggest? Are there any alternatives? Also considered Vredstein Sportrac 5s, for £73pw, which seem to score similarly to the Hankooks on tyrereviews.co.uk and Bridgestone Turanza T001s at £77pw.
Only Conti I can get in my size is the now ancient PC2. Same story with Michelin, with PS3 being the only option there (and at £105pw). Don't trust Dunlop Sport FastReponse or BluResponse as unhappy with them on a much lower power car.
