22,000 mi is about 35,000 km. Looking at my records, it looks like I drive 18,000 km per year. My tires generally last about 3-4 seasons, but it looks like I have the winter tires on about 8 months of the year (I'm just looking at archived data of temperatures by month for Vancouver, and I change the tires at 7 C). One third of the year on the all seasons is about 6,000 km per year, so I'd expect 18,000-24,000 km out of the all seasons. I replace the all seasons when I get to the wear bars, and I replace the winter tires when I get to the snow wear bars (these are taller than the other wear bars, so replacement is earlier). I choose the tires that Tire Rack says provide the best wet/ice/snow traction, which probably come with shorter useful life.
If tires get harder in cold temperatures (necessitating winter tires), I guess if you were in a hot climate, your tires might wear faster. Okay I looked it up. Tires do wear faster in hot weather.
From what I can tell without going into the garage, the Dueler that came on the 2018 has a UTQG of 300AA. So the tread should last 3x as long as the control tire. There is extrapolation about the expected tire life but here's one explanation:
Find out what a UTQG rating is and why UTQG ratings are just one of several ratings to consider when making sure you choose the right tire for your needs.

24,000 km seems really low now that I think of it, but knowing that the tires that come on the car are cheapies, I'd expect the replacement tires to last longer. Maybe I'm off a bit and the winter tires are on only 6-7 months per year. I don't think I've purchased more than one set of all-season or winter tire replacements for the same car. I had my 2007 Forester for 11 years, and I think I purchased two sets of winters, and maybe one set of all seasons. I traded that car in at about 160,000 km.
