Hello Reifengemeinde I would need 2 new tyres for the summer. Size 235 35 R19 91y My selection would be on the following 2 types. 1. Goodye F1 supersport 2. Conti sportcontact 6 My question is whether there is a test where both compete against each other or from your experiences. It would be nice to know which one also achieves a higher mileage. Thank you.
