What is the difference between “All-Season” and “All-Weather”?
All-Season tires are not designed for severe snow conditions. They are designed to have acceptable snow capability while providing the best performance in summer conditions. Although most All-Season tires have an M+S (Mud and Snow) rating, they do not meet the Severe Winter Service Traction Standard. Recently, Nokian introduced an All-Weather tire, the NRW. It meets the new Severe Winter Traction Standard, yet can still be run year round. It was originally designed for year-round use in Finland, the home of Nokian Tires. The NRW was one of the tires reviewed in 2001.
