I bought a set of four tires for my partner's Astra SXi and so far am impressed with them. You get great feedback from the road and you feel like you make a contribution to where the car is going when you steer.

Need some new tires for my Zafira so I am going with these too. Reasonably priced too considering they are a premium tire with "eco" benefits. I've yet to see the "benefit" yet but we shall see! I get a warm fuzzy feeling I am contributing to keeping this planet green anyway. ;-)
