Hello, A new version: I would like to mount summer tyres at the front and winter tyres at the rear soon for 2..3 months. Reason: the car is sold and it should not be upgraded by new tyres, since the price is already fixed… 1 pair of good (5.5mm) and 1 pair of less good (2.5mm profile) summer tyres are available, as well as 4 good winter tyres. Alternatively: the summer tyres with less profile on the back or the winter tyres continue (we already had yesterday…) the ADAC and my tyre dealer recommend new tires is logical, but do you have experience with this mixed tire? Greetings, Peter
