...the WRG3 from Nokian are the only tires that meet your criteria, as I understand it.
I've owned two sets of the Nokian WRs (Gen 1 and 2) on a '04 pathfinder, and I can tell you that those tires were a beast in ALL weather conditions. I don't know how they (Nokian, A Nordic based company) did it, but they made a great ALL WX tire, not just an all season or 3 season tire.
Nokian is famous for their winter only tires (Hakkapeliitta comes to mind), but they have great year round tires too.
I have drunk the Nokian Tire kool-aid and I am a believer. When the time comes to replace the Toyos on our 2016, you can bet I will researched the Nokian option.
However, with that said, Nokian tires can be expensive...more expensive than some well known brands AND at times, eclipse even Michelin tires of slightly less capabilities. Each of our sets were north of $800 + taxes.
Another downside to the Nokian tires is their availability and their dealer support network. Locally, here in OH, the Grismer tire company sells the Nokian tires and as long as there is a Grismer around, I can get find Nokian tires. There are other retailers of Nokian tires, but you may have to use the Nokian website (
https://www.nokiantyres.com) to find one close to you/your city. But I can tell you they are not as common as other tire brands.
One other thing I noticed, and it may have been because of the Pathfinders odd size (255/65/16) the first set of tires purchased happened to be just shy of 3 years old. I got some $ off, but the fact that those tires had been sitting somewhere for almost 3 years tells me that Nokian is not a high volume tire mover, at least here in the States.
Also, when my GTI is up for its 4th set of tires, I will be torn...I'm going either Michelin Pilot Sport A/S4s or WR-G3/G4. Granted, not the same as winter performance is concerned, but the Mich PS A/S3s that are on it now have been flawless and I can't complain (except for price). The car is daily driven and far from being a racecar.
