Hello, first of all I have to admit that I drove my winter tyres this year also in summer because they have not had so much profile. I am clear why you should not do this better. Anyway, now I have checked the tyres again and found out that these dissolves (see pictures in the appendix). DOT is in mid 2007. Both wheels are affected on the front axle. Question: Is this normal or must be reckoned with such “resolutions” if you have the Wi so I have to buy new winter tires now, anyway planned, and to choose from the Conti TS850, Dunlop D4 and Michelin A4. Size is 205/55/16 non RFT for the 318d e91.
