OK, I have searched the forums and found some older threads but I thought it was a timely time of the year for this topic. I am thinking of taking my AWD V6 Passat CC to the snow. Does anybody know whether chains fit the run flat Conti tyres? Do you need chains at all? I am concerned about the frameless windows sticking. What do I do about those? Anything else? Would love to hear from anyone who have taken their Passats (whether CC or not) to the snow...
