If your area gets just one or two winter weather events per season, you can probably get by with all-weather tires instead of actual snow tires. These won’t be as intense as winter tires, but they are sturdier than regular all-season tires. If you’re looking for a decent set of all-weather tires, Michelin CrossClimate 2 tires are a good bet for your Crosstrek.
No matter what tires you sport for the winter, make sure to change them back to all-season tires when the snow melts. Winter tires are meant for winter conditions only, so driving with them in warmer weather causes decreased performance and faster wear—leading to pricey repairs and more frequent tire changes.
