Hello together, my debut unfortunately has to start with a (perhaps) totally stupid question. In one to two weeks my A7 BiTu is ready to pick up and has currently 20′ summer bikes on it. (Is an annual car). Now my plan as a summer tire 20′ BBS CH-R is to buy and then to have the summer rubbers drawn up by the currently on the vehicle. So I would have to buy only for the current rims winter rubbers and would have two for me perfect wheel/re ifen combinations. As far as the theory is concerned. Now the ride from Coburg to Munich with almost 300km from the distance is the smaller problem, if only it were not such an unpredictable winter at the moment… Because as an old BMW driver (without x-drive) I am naturally afraid of the snow, even with winter tyres. Now the (dirty) question: is the all-wheel of Audi so good that even with snow with summer tires you are safely on the road? Would my car not like to be placed in the control plank at the transfer into the control plank. then, or worse… First of all thank you… SR
