POLARIS 5

Bought these tyres last year for my 2015 520d, id never buy them but my tyre shop was selling them for really cheap with little bit older dot (2023), seemed good for ice and snow, rain is ok but during heavy rain i didnt feel much what the tyres were doing, on autobahn when you first hit some snow on the road going over 80kmh the car would wiggle a bit but then it was stable, comfort and noise are ok but there is a really annoying noise from the tyres above 130-140kmh.
Overall i would not recommend them as they cost as much as hankook or falken, but the polaris 6 seems to have a lot better reviews than polaris 5 so it might be a much better tyre.
They are still above 8mm tread after around 5000-6000km so wear is good.

Ideal tires for my car. I have them for fourth winter now and i think they will last me for at least two more. I drive a lot on highways. I feel safe with them on snowy or icy roads.

I had the tyres fitted to my company car for 3 winters. They were mediocre and wore the exterior belts quite quick.

worst tyres ever i have. changed 7 year old michelin alpin to new barum polaris, and in all conditions it worse than old tyres was.
this tyres are actually dangerous, should not allowed to sell. what they doing in wet roads is totally dangerous! in +2-5 celsius wet roads absolutely no traction.

I'm not going to buy them again cuz they're very loud inside the car, even at 10 kmh. They make a very low, base level thud and rumble as if the town fanfare beat 3 big drums... I've only driven them once, it was in the wet. They were brand new.
I've driven them on my Dacia Lodgy (2013 model). I had just replaced my Semperit SpeedGrip2 with them. I had driven on Semperit SpeedGrip2 for 3 winters, those were very quiet.
