I have a friend who drives a 5-series RWD with a set of Blizzaks, he has never had problems in Boston winters. Any other thoughts? Thanks in advance.
Snow tires are necessary regardless whether you have X-Drive or not. The common mistake is to run the summer tires in winter thinking that you have AWD. AWD only helps you get traction, i.e. to start your car. However, you need proper tires to grip on to the road when you want to stop your car. Summer performance tires turn rock hard below 4 degrees Celcius and are not suitable for driving in the winter.
