Tires Nokia or OEM Porsche

I've had the Nokian WRG models for the past 10 years and there's always been a song and dance with each model I tried. The WRG3 were excellent in the snow but the treadwear and dry performance was average (Enough for my driving needs, however). The WRG4 were slightly worse in the snow compared to the WRG4 (Still decent) but leaps better in dry performance and rain. The problem with the WRG4 was the susceptibility to dry rot and overall "wear" from normal driving. They have been punctured, misshapen, and suffered "premature" treadwear compared to what was advertised as the expected tread-life of the tire. But given how well they perform in my 4-season climate state, I would rate them highly. Tire noise is minimal, performance all around is outstanding, and minimal diminishing of performance through treadwear.

We have studded Nokian hakkapalitta, love them.

I won't drive on anything but studded Nokian tires now.

Nokian Hakkapeliitta studded would be my #1 choice. Best winter tire imo.

Had blizzacs for years. Got studded Hakkas never going back.

From my experience, Nokian makes the best winter tires. Once you use winter tires on slush, ice and snow, you will never go back to all season tires in winter. With AWD, it's more about being able to turn and brake in slippery conditions than getting started.

I’ve owned 5 sets of Nokian tires and never a single issue with dry rot.

I went with Nokian outpost APTs. only had them for a few weeks and they handle just as well as the road tires I had on previously.

You can take a bigger hit in tires alone. For instance, on my stock ContiProContacts, I average 27 mpg with 235/50r18 tires. Same size but with Nokian Z-line A/S, a tire that grips the road much better wet and dry, I'm lucky to hit 25 mpg, usually more like 22 mpg.

No experience with the Continentals but I really did not like the Nokians. I bought them because they seemed to be well-reviewed, they were only marginally better than the Nexens in terms of traction yet they were a decent bit louder. Despite having plenty of tread left after 35k miles I replaced them with Michelin Primacy Tour and they’re so much quieter and the traction is much improved. I had a friend who is a frequent passenger in my car comment on how much quieter it was completely unprompted the first time he rode in the car after getting the Michelins. The Nokians were loud from the beginning and traction in wet conditions decreased rapidly as they aged.
