"....I truly believe that Nokia, a Finnish tire builder, produces the best winter tires in the world. The Nokia Hakkapeliita 10 was absolutely marvelous in the snow, despite having been developed years before the RMA established their new standard for winter performance. Its traction and response in the most foul weather was akin to a professional rally tire. The only downside was that the Hakka 10s were very, very noisy.
Hakka 10s have been replaced by a newer model (Hakka 1s) that provide even better performance, with quieter ride and better directional stability, than earlier models.
Gislaved Nord*Frost 2s are available through most Volvo dealers and have done extremely well in recent Scandinavian tire tests, beating Nokias on several occasions. I believe that Nord*Frost 2s are worth more than a glance when shopping for winter tires.
Bridgestone Blizzak WS-50s are acceptable, with this tire's degree of market penetration a testament to aggressive advertising. Blizzaks will certainly outperform any "all-season" tire but are not in the same league as Nokias or Gislaveds. The same can be said for the Dunlop Graspic and Pirelli Winter S.
Speaking of winter tires, it is not uncommon for a Volvo with a good set of winter tires to be able to easily out accelerate just about any Audi, BMW or M-B in the snow. North American muscle cars cannot hope to keep up with a well shod Volvo operating in snowy conditions. This is not to say that one should buy tires to win stop-light wars, but the added performance of the correct tire is welcomed by many owners......"
