I have the Nokian A3 on the back of my 9-5 and all-round on SWMBOs 9-3 Vector.
I bought them as they are sold as winter tyres by Nokian. Nokian also do a similar tyre that they call
"All Weather Plus". However, when I was fitting the
A3 winter tyres to my 9-5, I noticed that that these "Winter Tyres" were also labelled "All Weather Plus" in small writing on the sidewall, as reported for the G2 above.
The other thing I picked up when browsing the web recently (and forgot to bookmark so I could find it again.....) is that one of the tyre companies stated that winter tyres only have a four year life. After that the softeners that give the cold weather flexibility and grip will have evaporated and the tyres gone hard. Perhaps another thing to add to the argument about running winter tyres all year if you do a low mileage.
