My Continental wide tires are all four all around on the inside (to the center of the vehicle). They are the original tyres of the MB sports package for E-Class (front 245, rear 265 width). The tyres are still good from the profile, in front I still have about 6 mm, back about 4 mm profile. The employees of the MB branch noticed this by chance and refused to drive with the Fz. I assume that it is a manufacturing or material error. If someone already had the same problem, please ask for feedback. Greetings, E-Gerri.
