My first post here....Need your help. I am going to Munich with me wife during first week of December. I am then driving down to Mayrhofen - Austria from the airport (200 kms drive). I have never driven in such cold weather and was wondering if my rental compact car (automatic - compact car) will be ok. Should I pay for additional snow tires or should I invest in snow chains. Any help will be appreciated as I am totally clueless.
