2016.5 CX-5 GT here, as well.
Like you, I live in a place that does get snow and ice, but it tends to not stay around for more than a couple of days. Once or twice a winter, it'll hang around for a week, but that's not that common.
In Denver ... If you feel the need to contend with some snow and ice during the winter months, and if you don't particularly want to do a second set of wheels/tires, then you might consider the
Nokian Encompass AW02, . It's coming in January 2025. It's available in the 235/50VR19 size, 103V XL, with a 65Kmi treadlife warranty. It's available at DiscountTire outlets; and it seems you've got some in the Denver area.
For the past handful of years I've used the Nokian
WR G4 SUV, 103V XL, 60Kmi treadlife warranty. It uses an all-weather, year-'round compound and has more winter-oriented siping. Exceptional in the wet, snow, slush, and fairly good in icy conditions. Not a straight winter tire, but has about ~90% of a winter tire's grip. Have used them in >100ºF+ and <0ºF conditions. The WR G4 has now been replaced by the
Remedy WR G5 (same essential tire). It's available in the standard GT's 19" sizing (225/55-19, as well as 235/50-19, along with a couple sizings in 17" if you prefer that size rim). My existing WR G4 SUV tires are at about 43Kmi now, right on track for its 60Kmi life (though I'll swap them out a bit sooner).
As I'm on my last ~12-15Kmi on these, I'm seriously considering the Nokian Encompass AW02 for my next set. Will decide by next summer/autumn. It's got the same 103V XL rating , better treadlife warranty (65Kmi), a bit less winter-oriented siping, but the same great all-weather, year-'round compound. I suspect it'll be better in the clear-weather "summer" months, be just as good in the winter, with a bit better tread life (than the WR G4).
"Summer" performance (with these WR G4) isn't quite up to normal summer-oriented all-season touring tires' handling capability, at least if pushed hard. Its siping and somewhat softer all-weather compound allows it to feel a bit softer in harder turns, but it's plenty capable (in 103V XL) if driven normally. (It isn't a "performance" tire, of course, so that's to be expected.) Otherwise, it's stellar. A good alternative to a typical 3-season type touring tire.
Great tires, IMO. Have had a set of the Nokian Hakkapeliitta winter tires before. Stellar in ice and snow, though they don't last long. Suitable as a winter-only set of wheels/tires, for people who have two sets in severe winter areas.
One option to "normal" 3-season (aka "all-season") tires.
