I guess it depends on how much you drive, but I wonder how well all the all-weather tires work down near 5-6/32?
I tried a set with the CRV and got down to 5/32 going into the second winter(they weren't great for the first) so I picked up a set of lightly used winter tires.
My 5/32 snows got me around OK with the Focus this winter, but that's the 4th and last winter for them.
I have the WR-G3 on my wife's Subaru and doing great, I sold my neighbour on all weathers and they use Hankook's up into Quebec without any problems. Not as good as dedicated tires, but a great compromise for those living in the cities of the snowbelt with the occasional foray into snow country.
It's basically a Nokian WR A4 made for the US/Canada market.
I forget a what depth does the snowflake disappear, probably around 4-5mm I would have to guess.
I had the Nokian WR G3 (with the WR A3 pattern), and was very reliable in the winter with a FWD car. Compound stayed nice and flexible in sub zero °F temperatures for me.
Yep, my corolla will likely be my around town DD but as a 2nd vehicle, so figured an all weather tire would fit the bill on my DD but will put dedicated snows on my newer car for longer treks.
