Nokian WRG3 All Season Tires
Nokian is not yet a well-known brand in North America, but they are the manufacturers of some of the best winter tires for the harshest winter conditions in the world. This Finland-based company makes the WRG3, which is ostensibly the closest you can come to a "real" all-weather tire.
That's right, the Nokian WRG3 is technically an all-season tire, but they perform better than many dedicated winter tires on the market. These tires will not deliver the same sort of summer driving performance as dedicated summer tires. However, they offer a surprising level of high-speed handling and very little of the tread squirm associated with winter tires.
Winter performance doesn’t match up to the dedicated winter tires from Nokian, but the WRG3 offers overall a good amount of grip in winter conditions. The ride is firm but smooth, and road noise is reasonably low. While these tires won't win any awards for objective performance in any season, they offer excellent all-around traction and handling with enough of a winter bias to make them suitable for all-year use.
