Hi all, first post here. I've been lurking as we're considering a new Rav4 Hybrid. I have some real world experience with the Michelin CrossClimate2 that I'm glad to share. SKIP TO THE VERY BOTTOM if you want to avoid my excessive verbosity and see the pseudo-scientific MPG results of my experience with the Michelins.
We currently use a 2021 Hyundai Palisade Limited AWD as our daily driver here in the Midwest. Our driving is mostly in-town suburban miles, and we drive more than average at about 19k miles/year. The Palisade came with Bridgestone Dueler HP Sport tires, and they performed acceptably well in all conditions including mild to medium snow and ice weather (first vehicle I've had in 20 years that I didn't get snow tires.) After a few road hazard incidents, including a nail that magically penetrated the sidewall twice, I decided to get a full set of new tires at about 35k miles. I was surprised at the amount of tread left, considering the warranty was only 40k miles. I don't remember exactly, but I know it was at least 60%. I didn't want to tempt the Hyundai warranty department by having tires with different amounts of wear (essentially different sized tires) so I ended up swapping out all 4 tires for a set of CrossClimate2s.
I don't have many opportunities to find the edge of the envelope while carting kids around in a 7 passenger SUV, so I can't make too much of a conclusion regarding handling. I will occasionally get after it, say, in an empty traffic circle or elsewhere, and the grip feels pretty confident, like there is better than average handling capability. (I autocrossed and other amateur raced for years and have a decent idea what to look for when I'm feeling out tires.) They handle quite well in rain and the limited adverse weather conditions we've experienced, including speed limit driving on unplowed expressways and in town. A noticeable difference was in the noise though; the Michelins aren't silent but they are definitely quieter than the Bridgestones were (especially on that awful 6 mile stretch of I-65 between Chicago and Indianapolis). And let's be honest - they look pretty cool too.
But if you're driving a hybrid, there's a chance that all of the above takes a back seat to effect on MPG. Fortunately, I've kept track of all the fill-ups, service, and mods to all of my cars in detail, so I can make some relatively decent comparisons. Of course MPG is affected by numerous other factors, including temperature, driving style, % highway vs city, etc. So the best I can do is look at the same time period and assume the other factors are all roughly the same. FWIW, I keep tires inflated on the higher side, like 38-40 PSI. I've done this forever and have noticed no abnormal tire wear or discomfort. ANYWAY....
seasonal comparison, tires installed at ~11/15/23
11/15/22 - 2/6/23: 5334 miles, avg 20.67 mpg (CrossClimates)
11/14/21 - 2/7/22: 4145 miles, avg 20.22 mpg (Bridgestones)
I checked the miles per day between fill-ups and saw that there were 3 "road trips" over 100 miles per day in each time period, so it's a fair assumption that the increase in miles comes from the increase in city driving. I can believe that, since my kids have really stepped up the number of activities they're involved in, which means we're doing a lot of in-town kid-taxi driving. But, I can extend the date range to even out the miles, and check the MPG.
11/15/22 - 2/6/23: 5334 miles, avg 20.67 mpg (CrossClimates)
11/9/21 - 2/28/22: 5395 miles, avg 20.11 mpg (Bridgestones)
And just for fun, I'll check the closest date range I can manage starting in '20 (we bought at the very end of November)
11/28/20 - 3/24/21: 5352 miles, 20.82 mpg (Bridgestones)
Considering that the factory estimate for combined mpg on this vehicle is 21 mpg, and that we do mostly city driving, and some amount of cushion for error, I'd conclude that the Michelins made no appreciable difference in MPG, compared to what the Palisade is "supposed" to be getting.

-----------------------------------------------------------------
21.00: Factory Estimated MPG (Bridgestones)
20.11-20.82: Calculated MPG, 3 mo. winter (Bridgestones)
20.67: Calculated MPG, 3 mo. winter (CrossClimates)
In my experience, the Michelin CrossClimates have not substantially affected MPG, politely or negatively. This does not mean that there aren't tires that have lower rolling resistance / improve MPG.
EDIT: FYI, our annual average MPG on the Bridgestones is 21.7, which would seem to confirm much more of a variation in MPG due to weather/temperature and seasonal gas formulation change.
