Hi John,
The tires that come with the car are truly NOT all-season tires. To be safe in Ontario (pretty much all of Canada really), you should get some actual winter tires to swap out seasonally.
The only
genuine four-season tires I know that are made in smart sizes are Vredesteins.
Visit
Vredstein vs EcoContacts - Club smart Car for some user reports.
Our member, "FastEddy" Lai's Flying Tiger Developments can set you up with
Vredestein four-seasons or
Continental snow tires at serious discounts from regular price right now.
Hope that answers your questions. (Well, other than why the dealers still keep calling the oem Conti's all-seasons when they are not all-seasons!)
