I know this all too well.

I bought my x5 with 255/55/18 Dunlop winter tires.

I was immediately accustomed to the capability of the tire.

We bought wife's x5 with "bargain basement" 235/65/17.

When I drove her car in snow it felt like a bad front drive. I had no sense of all wheel traction. When I took corners like I always do in my car, her car would under steer over steer do anything but track a radius. It also just handled like total crap.

I bought a new/ish set of Dunlop winter tires for my car but also a new set of rims so I put my rims and tires on her car.

Holy crap it was absolutely night and day difference! I thought the handing difference had more to do with mine having the sport suspension.

In a blast from the past. The first car I drove as a teen was an Impala and it had 235s until one day dad found a deal on some barely used 225s.

The very first time I stopped firmly at a yellow light I probably should have gone through, obstacle like instantly locked the brakes; not even close to the same amount of force I used daily.

I'm a little surprised if the 6 is pulling off this feat but I think the odds are in the fairly likely class.
