Re: Snow tire sizing problems
Its not unusual for tire shops to install tires that are one size larger than stock, probably only because they cost more, but most of the year its not necessarily a bad thing since they give better traction. In the snow however, you should run the narrowest tires possible for a couple reasons. A narrower tire has less resistance pushing through snow, and by distributing the cars weight over a smaller contact patch narrower tires provide better traction on ice. If you get new tires, go for 185s.
Tires are an example of something where its well worth it to buy the best you can afford. Pirelli Winter Carving tires, have pretty good ratings and Pirelli is a great manufacturer, but they are on the lower end of winter tires. I personally use Nokian Hakkapeliitta R winter tires, they`re expensive, but driving through snow drifts feels like driving on asphalt. At my local shops they are around $300, or online for $200 if you can someone with them in stock.
