Nokian Hakkapeliitta 8! Mine are studded, awesome grip in snow, 255/35/20 all around....

Cool! Wish I had known about these before. How's it handle driving on dry surfaces?

guy in the vid is a knucklehead

going UP beacon hill is also not a smart idea. zero control with unplowed roads. my 3 year old has more control on skis

Frankly surprised about the dry grip in cold weather, needs some adjusting after the PSS u can feel the flex in corners but ultimate grip is good. Better dry handling than the sottozero and X-Ice.... More compliant ride than the PSS.

Nice! Yeah the Michelin Pilot Alpins do ok in the snow, not the best, they definitely keep you from getting stuck, but boy are they fantastic on dry pavement. They perform nearly as well as the PSS do on dry surfaces with the exception of being able to have enough traction for the insane amount of torque the M5 produces, especially when going full throttle. Still the studded tires would be some very nice peace of mind of knowing you are not going to get stuck no matter what.

I was caught in Freezing Rain with PSS2's (save the lectures; wasn't trying to defy physics or common sense).

All was fine with caution taken, including a 14% incline with at least 3/4" of ice. It wasn't until I went inside to retrieve the garage door opener and grab a cup of coffee that things went...well nowhere. Not even a 1/2" of snow accumulated and the car would not budge. Not even on a flat surface. It took 9 hours, 80lbs of de-ice, and 40lbs of kitty litter to finagle the car 15' inside.

After that I wouldn't even begin to consider an M5 with SMG, winter tires or not, in anything more than a light dusting.

I drive a stick so no gear lock out issues for me.

Curious what PSI do you run? My dealer installed them with 34 PSI and I found they flexed quite a bit. I checked Nokian's website and they recommend +3 PSI over summer tires. I've been running 37 PSI all winter and they feel a lot better.

+1 put mine on last October and not regretted it. Used to leave my E70 X5 in the garage if it snowed as it was crap .. but never changed the tyres on it. Wife drives a Mitzi Outlander and it is awesome in snow with ordinary road tyres

Anyway 2 weeks ago, I was pissing about in the snow in the M5 with these Alpins on .. and pretty impressed ..

First year running a car this powerful in snow,
still learning along the way!

sottos are terrible in wet conditions especially snow. Either use blizzaks, Alpins, or mothball the car for the winter. the number of stranded cars on the road are too damn high
