Replaced all 4 stock Michelin Primacy all-season tires with Nokian WRG4 all-weather tires yesterday. Have driven 350 km already. Noticed no difference in the noise/harshness, or range in the Model 3; but do think there is less understeer now on the same roads and off-ramps compared to the original tires. Overall, a noticeable improvement. If my past experience on the previous generation of these Nokians is any indication, I know the new WRG4s will handle my SW Ontario winter driving much better than the stock all-seasons, which I will not miss.
