We've gt them on the S60. They're quiet and work well in the snow. They are all weather tires, and not dedicated snow tires. But they are leaps and bounds better than the Continental tires they replaced. Can't really comment on the longevity, she doesn't pile the miles on very fast. The WRG2 and WRG3s I had on the S70 we used to own lasted 40k-ish.
Nokian garbage will never go on my vehicle again. I gave them chance three times thinking they got their at together, but nope.
While new they are fine, but decline in performance from new to absolutely abysmal makes them serious competitor in that "discipline."
I had the WRG4 tires on my 2018 Outback for 80,000 miles and probably could have gotten at least an additional 5,000-10,000 miles on them if I wanted to push it. They are absolutely phenomenal in Winter driving and well above average in all other conditions. They are the next best thing to a dedicated snow tire for snow driving.
Buyer beware though, these tires are noisy at highway speeds. About 50 mph there is a very pronounced droning noise that does not go away, in fact it only gets worse as the speed increases.
I'm shopping right now for new tires for my 21 Outback and while I'm a huge fan of the Nokian brand I will not consider the WRG4 tires this time because of how noisy they are. I will probably go with the General Altimax 365 if I go with another all weather tire.
I have thought about the CC tires as well and while everything about them seems great, the guys that work in my shop don't like them in particular because of wear they've become accustomed to seeing on that tire and the opinion but they become noisier as they wear down. I've been very tempted to buy that tire but I'm a little worried that I might end up being disappointed especially considering the extra cost associated with purchasing a set.
