First off I’m in Alaska and have used Nokian winter tires almost exclusivly for as long as I can remember. They are the best winter tires. Between our cars I currently have vehicles with Hakka 4,5,7 and 9. So my Hakka 7’s are technically the 7 SUV.
For the studded tires the hakkapeleta-9 is the current, newest tire.
The Hakkapeleta “number” (like 7,8, 9) are the p metric tires and studded for passenger cars. The hakkapeleta “number” SUV are p metric tires in larger sizes for trucks and suv. All the nokian p metrics are XL designated so have a higher than normal load rating.
The Hakka LT2 is the same studded tread pattern as the Hakka 7 but a 10 ply LT tire.
The Hakkapeleta R3 is a studless winter tire and from what I hear is very well recieved.
Nokian also have a “budget” tire called the Norman. It’s an older hakkapeleta with a different name. The current One is the Norman-7, it is a Hakkapeleta-7 renamed.
My Hakka 7 SUV are about 5 or 6 years old I got them on a deal when the 9 came out and I couldn’t get the 9 in my size.
We have Hakka 9’s on my wife’s new Tesla and their breaking performance on ice is absolutely amazing. I started this winter With 40-50% on my wear indicators on my 7. Next winter I’ll get new winter tires for my 200 and it will most likely be the Hakka 9 SUV.
I’ll also add I run BFG KO2s in the summer that is a LT tire but I pull a 7k lb camper all summer and don’t tow in the winter so don’t feel the need for an LT winter tire.
I hope this helps.
