Dear Doctor: I’ve been told that all-wheel-drive cars cannot use tire chains or cables. I have a Subaru and Ford Freestyle with AWD and live in an area where there is a lot of ice and snow. I’d still like to use tire chains. Is this advisable? Donna
Dear Donna: There are light-duty straps that can be attached, but they must be put on all four wheels. I do not recommend the use of the old style heavy-duty chains on AWD vehicles. I suggest you buy a separate set of black steel wheels with an aggressive snow tire. I prefer the non-very-soft ice compound for the winter driving season. The very-soft ice design snow tire has a rapid wear factor when driven on dry asphalt roads.
