Tires Nokia or OEM Porsche

Nokian is better on Snow and ice, less tread life

Michelin is better on wet and dry, but still decent in snow, better tread life

Have a look at the Bridgestone Weatherpeak as well, better tread life and easily comparable to the Nokian in snow and ice.

The Nokian Nordman are great aswell, would argue they are bit better than new Hakkas when there is wet snow on the road (ice and compacted snow, both great).

I just came across this post after ordering a set of Nokian WR G4’s. This will make my fourth set over the years for different cars, and absolutely love them. Great grip in snow, ice, slush, etc.

I put them on my Clarity and they're every bit as good as the Michelins they replace at half the per mile cost. They even are a bit more efficient.

I have Hakka R5's on my S5 and doubt I'll be going back to anything else. They've handled winter here in Alberta very well so far.

I can also vouch for Toyo Observes, used those before switching and I had no complaints.

Studless are what's up. Nokian studless hakkapalitas are the best snow tires I've ever owned.

I have Blizzaks ws80s on my Focus ST, and hakkas on my wife's Edge. When the Blizzaks are done, Hakkas are going on.

My previous car was a Legacy wagon on studless Hakkas . Driving in crappy Alberta winters was a complete non-event.

I run Nokian winter tires on my vehicles. They've been nothing short of spectacular through more than a decade of driving the Northern Rockies in winter. This is excellent news!

I like studded snow tires and have had some nokian tires for a while and like them alot, enough to get a set on our subaru as well.

Not a fan of Nokian, they slip like crazy. I have some of their all seasons on my RX350 and they are like hockey pucks, just sliding everywhere.
